> According to Waymo, the company’s vehicle fully stopped at a four-way intersection before proceeding into the intersection as a large truck was driving through in the opposite direction. “The cyclist was occluded by the truck and quickly followed behind it, crossing into the Waymo vehicle’s path,” the company said in a statement. “When they became fully visible, our vehicle applied heavy braking but was not able to avoid the collision.”

Sounds like it should have wainted for the truck to fully pass then or am I not understanding the situation correctly? Would love it if they released the footage of the accident though

very surprising that Waymo would describe the accident in terms that blame the other party
Why? If you don’t follow the rules of the road the cyclist is to blame. Now what Waymo needs to do to avoid this in the future is a whole other discussion…
Waymo needs to do nothing to avoid this in the future if their vehicle was following the rules of the road and the cyclist did not.
You don't think that they should try to avoid avoidable collisions?
Every collision is avoidable if you drive the car at 5mph at all times. But that wouldn't be reasonable. If the Waymo description of the incident is accurate, there would be no way to really avoid this accident without significantly nerfing the normal and expected driving behavior of this vehicle. e.g., you would need to not allow a Waymo vehicle to enter the intersection when there is any other vehicle in it as well, which (in my opinion) would not be reasonable at all.

If it drives better than a human (in this case it sounds like it probably did), that's good enough for me.

You may want to look into the concept of the "Failure to Avoid" or "Failure to Reduce Speed" citation. These encapsulate scenarios where it there was reasonable opportunity to avoid or stop before causing a collision.

You don't just get to careen into a collision because someone else is not following the rules of the road, hoping for a payday.

Ok, but neither of those things apply in this case.

Obviously Waymo vehicles should be slowing down to try to avoid a collision / reduce the severity. But in this case it sounds like the "fix" would be fundamentally changing the cars behavior to be far too conservative.

Sounds like the cyclist didn’t stop at the intersection or follow the rules of right of way.
I am usually one to bash cyclists for not following the rules, but I believe it's actually legal for them to do this at stop signs. They only have to slow down and check for crossing traffic before going through.
California requires bicyclists to come to a full stop at stop signs. There's no stop-as-yield here.

Even in places that do, they still require bicyclists to yield right-of-way to any vehicle stopped at the intersection before they arrived.

> They only have to slow down and check for crossing traffic before going through.

As another poster said, this is not true, but more importantly…

Some cyclists treat the “yield at stop sign” concept as “yield to me the cyclist, as I will not slow down unless I have to, and I will be unhappy about that”.

I’ve been cursed out, flipped off, and given the evil eye when I pulled out from a stop sign and a cyclist that was far up the road when I looked had to hard brake because they weren’t even slowing down.

I’m all for cyclists rights. I was a bicycle messenger one summer, and my replacement was killed in an accident. Being a cyclist can be dangerous and scary, but some cyclists just act like entitled shitheads. Besides being a problem for all folks on the road, they also give cyclists a bad rep.

It is pretty common to see people go from the opposite side of a stop sign since it's "safe", even if it happens to be against the rules. I can understand how the Waymo AI would end up being configured to do this. Hopefully they amend that based on this incident.
I don’t know about California but that’s legal where I live. Vehicles on opposite sides of a 4-way stop can enter simultaneously if both are going straight.
The way Mo was turning
From my reading of the statement, the truck and Waymo vehicle were both going straight, in opposite directions. The cyclist was traveling on the cross-street and entered the intersection directly behind the truck and into the path of the Waymo vehicle.
I'm pretty distrusting of where people will use turn signals in general.
> It is pretty common to see people go from the opposite side of a stop sign since it's "safe", even if it happens to be against the rules.

Where is it against the rules?

Is it not against the rules to drive into an area that you do not have proper visibility?
(comment deleted)
Any vehicle blocks the visibility of a 5 year old, as I often remind my kids.
That's why I said "if"? I don't know the laws of the road in all 50 states. They vary a lot.
(comment deleted)
Cant believe these things are allowed on the road...
What’s the relative likelihood that a waymo car will hit a cyclist or pedestrian vs a human operated car? Unfortunately for us cyclists, people are hit by human drivers every day.
I can’t believe those things are allowed on the road!
I can't believe we have roads in the first place. It is the invention of the romans. And what good have they ever done for us?
Possibly, perhapsily, they left someone behind in England who became the seed of the King Arthur stories, and those are pretty good.
I'm guessing lower - the Waymo car started braking aggressively as soon as it saw the cyclist, and the cyclist escaped with only scratches. Given our slower response times, the cyclist probably wouldn't have been as lucky with a human driver.
I looked up the cited street in street view- there are stop signs in all 4 directions. I look forward to the full accident report, but from the evidence available it sounds like the cyclist didn’t stop at the sign appropriately.
[flagged]
i think cyclists should have equal share of the road and should be protected but for whatever reason cyclists in SF seem to think the rules don't apply to only them and will get militant if you breath the wrong way.
Yeah I cycled frequently there for 5 years and always wondered what was wrong with that faction
As someone who bikes on 17th street regularly, cyclists rarely stop completely. Most treat it as a yield (myself included) because it's a pain to start+stop at every stop sign.

But it's on the rider to make sure you're on the same page as the other drivers at the intersection, which some bikers don't and just blow through it without checking.

Same, I take the wiggle all the time and definitely bully cars into letting me keep going :/
Harder to do when the driver of the vehicle is not a human being you can make eye contact with, and the human operator isn't interested in maintaining safe and attentive authority over the vehicle that they are responsible for.
I feel like I'm the only person in my town without tinted windows. I never see other drivers faes whether I'm driving, biking, or walking.
Is your town in California? Cuz that would be hella illegal for their front windows and windshields to be tinted to the point you can’t even see their faces.

https://www.californiacarlaws.com/window-tint/

It's somewhere between "moderately" and "hella" illegal just about everywhere in the northeast, but people still do it all the time.
It’s barely enforced, and I believe that in most major California cities they can’t pull you over for it now, but can give you a ticket if there’s another reason for the stop. The majority of cars I see that are under ~5 years old on California roads have illegal tint.
If cyclists go through without coming to a complete stop (like 99% of drivers, complete stop means the wheels are not turning and the speedometer says "0") and gets hit, the cyclist/pedestrian dies.

If a car ignores signals, the cyclist/pedestrian still dies.

These are not the same modes of traffic, and forcing everyone on earth to bend to the behaviors of the most dangerous mode of transportation is insanity.

> Most treat it as a yield (myself included) because it's a pain to start+stop at every stop sign.

Sure. It's a pain for cars to start and stop at every stop sign too. So?

I drive and bike. It's more annoying on a bike to come to a complete stop.
I find plenty of rules of the road annoying, whether I'm in a car, on a bicycle or pedestrian. This "Oh, well, it's annoying so we don't do that" is BS.
I used to yield at stop signs early on while cycling, but after I was hit by a car who ran a stop sign, I switched to coming to a complete stop at every stop sign, ensuring no cars were about to run their stop signs, then going. Self preservation is more important than maintaining a little bit of momentum.

A fun bonus for this method is it seems to annoy the cars behind you even more when you actually come to complete stops, even though all drivers complain that cyclists don’t stop at stop signs.

Very very few drivers respect speed limits to the T or the whole bunch "slow down when you do not see around" rules.

So, majority of drivers can stuff themselves when they suddenly demand absolute perfect compliance from non-drivers.

If someone can't follow traffic laws, they shouldn't be on the road (regardless of mode of transportation)
I see quite a bit of cars not coming to a 3 second stop, they mostly roll at slow speed and never actually stop the vehicle completely.

Do you advocate for 70% of the drivers to be taken off the road?

(comment deleted)
The law is a complete stop in California, not a 3 second stop.

And yeah, anyone rolling through stop signs shouldn't be driving. In cities that actually enforce traffic laws, you can get your license suspended for it.

And since this is about (semi-) autonomous vehicles, in this case, lets not also forget the release of FSD that specifically allowed you to run stop signs.
So anyone who drives 1 mph over the speed limit shouldn’t be on the road?

There are laws and there are norms. The overlap is never exact.

The laws should overlap with the norms more.

It really bothers me that the laws don't reflect real life. It gives the authorities the ability to harass whoever they like for violating laws that are routinely ignored until a cop wants to start something. That's not okay.

(comment deleted)
Insisting that a bicycle needs to follow the same procedures as a 3000lb internal combustion engine driven vehicle is madness. The vast majority of car laws are completely inappropriate for bicycles. Bicycles are much smaller, go much slower, can stop much faster, etc.
[flagged]
Then ride in dedicated bike lanes, but don't make up excuses why you should break the laws just because they are inconvenient to you.
(comment deleted)
confine the bikes to the bike lanes, then don't build bike lanes (or build awful ones) and finally you'll be free of those pesky bikes! finally the cars will have the road all by themselves.
> don't make up excuses why you should break the laws just because they are inconvenient to you

I tend to agree, and obey the speed limit and come to a stop at stop signs when driving. I get passed by other drivers, sometimes dangerously, often illegally, several times a week.

I would have sympathy for driver complaints about cyclists who ignore inconvenient traffic laws if drivers were any more law-abiding.

If you want to drive faster, fine, change the speed limit. But don't just ignore laws you find inconvenient!

I get what you’re saying but as a cyclist totally disagree. The problem I see at least while I was in SF, cyclists generally believed since they were riding a bike, they had the right of way in all scenarios. I still have vivid memories of almost smoking a cyclist while on my motorcycle only for them to be mad at me when I tried to explain to them that zipping in between lines of cars will get them run over. If you are to mingle bicycle son the same roads as cars, they need to follow the same rules.
> I drive and bike. It's more annoying on a bike to come to a complete stop.

That's a side effect of your choice, not an excuse to blow through stop signs.

It's also a side effect of very bad urban design. I bike in the Netherlands and don't know if I've _ever_ seen a stop sign here. Traffic signals, sure, but not stop signs.
Cities in Europe are much smaller and more compact than US cities. And while there's no stop sign, you still have to yield to traffic from your right if there's no sign whatsoever. And specifically, dutch cities tend to have winding narrow streets where you can't speed up too much.

Stop signs are put in places where I guess a yield sign proved to be dangerous to traffic?

True, but you're addressing some of the things I meant when I said US cities have very bad urban design.

The alternative isn't a yield sign, it's a redesigned intersection and likely a roundabout, or much smaller intersection, or similar.

How is it a pain to stop in a car? Does your foot hurt from pressing the brake pedal and then the accelerator? I don't get it - it takes actual, not-insignificant effort to start riding a bike after a full stop, unlike a car, even when it has a manual transmission. I'm guessing that is why there are jurisdictions that introduce laws allowing cyclists to skip the full stop.
But it's on the rider to make sure you're on the same page as the other drivers at the intersection, which some bikers don't and just blow through it without checking.

I've seen this behaviour a lot. Several times I (walking) came up to a 4-way stop, stopped there briefly to see the cars in the other direction slow and stop, and then started to cross and nearly got hit by a cyclist who seemed to have not seen the stop sign at all.

If you choose to blow through the stop sign because it "looks safe", you should bear the full responsibility for that decision. (I say this as an avid cyclist who sometimes blows through stop signs.)
> you should bear the full responsibility for that decision

That's not fair to pedestrians or other cyclists who can be injured by your decision to break the law and ignore their safety.

To clarify, the cyclist is the one breaking the law here.
I understand that. That's why I said they're a danger to pedestrians and cyclists, not cars.
>avid cyclist

Why do I only see this phrase when someone is blaming cyclists? I bike everywhere but I'm not an "avid cyclist", it's just a tool for getting around. What is there to be "avid" about?

I suspect it's from people who think of cycling primarily as a sport or pastime, not a practical mode of transport.

>If you choose to blow through the stop sign because it "looks safe", you should bear the full responsibility for that decision

This is the "you're holding it wrong" mindset, where something doesn't work right, and people are blamed for not contorting themselves around it. If it looks safe, but isn't safe, then that's a problem with the road, not the people who use it. It should be redesigned.

4-way stop signs are stupid, there are better alternatives like roundabouts. UK and Europe have hardly any stop signs.

by that I meant that I cycle regularly (both for sport and transport); in other words, I'm not criticizing cyclists from the sidelines
> 4-way stop signs are stupid, there are better alternatives like roundabouts. UK and Europe have hardly any stop signs.

wholeheartedly agree, and just in general there are too many stop signs in the US;

but what's needed for cars going at 40-50 Mph is different than what's needed for cyclists who have the time to look both ways without necessarily having to come to a full stop (just like pedestrians crossing the road at places other than a crosswalk).

Are you implying that we shouldn't be concerned about automated vehicles hitting cyclists if the cyclist wasn't following the lawn to the letter?
According to the Waymo description, the cyclist was behind a truck, and not visible to the Waymo car.

If that's true, then a human driver likely would've done the same thing: take its turn at the stop sign.

In most of my defensive driving classes, they tell me that if I can't see it, that means there's probably a car there.

So a safe human driver would not have entered the intersection while the truck was obstructing vision.

That may have pissed off the people behind me, but at least I wouldn't be turning while blind.

If Waymo's description was accurate it wasn't blind when they entered the intersection. Waymo and the truck stopped at a 4-way intersection traveling opposite directions. Both entered the intersection going straight. In the meanwhile the bicycle entered from the cross street behind the truck, himself blind to what was occurring in the intersection.

We'll have to wait for more information to see if that description is accurate, but the car's action was a legal and safe thing to do based on the description given.

> but at least I wouldn't be turning while blind.

There is nothing in the article suggesting that the waymo was turning.

Edit: Nevermind I was visualizing the direction of cross traffic incorrectly. The cyclist's lane would have been to the left and closest to the Waymo, which means that the truck must have already been in the intersection when the Waymo started moving if it was obscuring the bike.

So either the Waymo got to the intersection later than the black truck and tried to sneak in a crossing, or they both got there at the same time but the Waymo came to a complete stop and then proceeded while the truck performed a rolling stop, or something similar.

That's a much fuzzier situation and will depend a lot more on details not being shared.

The cyclist and truck were turning.
Cyclists can treat Stop signs as Yield signs in California.
Not legally. There was a failed push for this to become law in the past.
No lies in the article. "The bill now heads to Governor Newsom's desk" ... where it was vetoed, sadly.
> where it was vetoed, sadly

Sounds like the gov did the right thing. Cyclists shouldn't get special privileges. They're operating a vehicle on the roadway just like everyone else. Drivers of other types of vehicles shouldn't also have to remember special rules just for cyclists.

> Drivers of other types of vehicles shouldn't also have to remember special rules just for cyclists.

Drivers of any vehicle should learn all of the rules they need to drive safely and legally. It's not like there's a hundred different types of vehicles on the road. There's some special rules for trucks and motorcycles and bicycles and that's about it.

Plus, travel by bicycle is a net positive for society and I strongly support incentivizing it, including through preferential laws (even though I almost never do it myself).

What are you talking about?

All road users do have different rules for using the road: peds, cycles, scooters, motorcycles, cars, cargo trucks, buses, trams, etc. all have specific rules applying to them.

There are restrictions on where bicycles can be ridden that don't apply to cars. Should we get rid of those laws too?

Let's also get rid of the lower speed limits for 18 wheelers, and weight limits on bridges. Why should passenger vehicles have all the fun?

How about lane splitting for passenger vehicles, just like motorcycles get to do?

An easy position to hold when it's physically impossible for a cyclist to harm you in your steel cage but you can kill them on a whim by slightly turning a wheel.
You can do that, but then you have to accept the consequences when things don't play out the way you had hoped.
(comment deleted)
Setting aside the fact that the bill that proposed this was vetoed, a yield sign does not mean "don't stop." Yield means "yield." If there is other traffic that has the right of way you are obligated to stop before entering the intersection.
Cyclists do this all the time in SF. Afaik an "Idaho stop" is not legal here, despite it being common and often unsafe for obvious reasons.
I've always heard it called a "California stop."
Rolling through stop signs while cycling is generally appropriate (and is the law in more enlightened places). In California it may be illegal, but so is a car exceeding the speed limit, and few would excuse Waymo for hitting one of those.
Only if you have right of way. You still treat it as a yield, which means if you don't have a right of way, you stop completely.
Rolling is usually slow enough to stop on a dime from my experience. The problem is cyclists who continue at full speed and then decide to react last second.
And I am willing to concede that on a bike, as long as you are just slow rolling and not impinging on the right of way such that it confuses other drivers, it's fine. But I have also seen plenty of cyclists who slow roll into the middle of the lane and then act indignant when they get honked at for blocking traffic; At that point, there's very little difference from having just blown through the intersection at full speed.
Yes there is a hostility between drivers and bikers and bikers and cars, where they both build up resentment and settled for this hostile middle ground where they both treat the others poorly.

Not to mention plenty of people in both are just dumb or ignorant of their surroundings

Just to nitpick a little, let's use the word cyclists, not bikers. I feel that bikers actually obey traffic signs more than cyclists do.
> Just to nitpick a little, let's use the word cyclists, not bikers

Humans are capable of gleaning from context.

> I feel that bikers actually obey traffic signs more than cyclists do.

Motorcycles have completely different traffic laws, both legally and socially... so yes they would follow car style traffic rules more closely than a cyclist.

Sounds like you're deliberately using a longer, more activist-sounding word to "other" people you don't like.
It is because I ride a motorcycle also I feel like putting me in the same basket with cyclists is not fair.
Cyclists are just dangerous and until we look at statistics we can’t assume that AI does worse than humans in protecting cyclists. As a driver, it took me many years to get into the habit of shoulder checking when turning right from the right lane. I always have my turning signal but to cyclists it doesn’t mean much, they will always try to pass me on the right on the intersection. Cyclists sometimes behave as though they are pedestrians and other times they behave as vehicles, depending on what is convenient. Or that may just be me trying to rationalize their erratic behavior. There are no traffic lights or signs for cyclists.
If you are turning across a curbside bike lane then you need to yield. A bike lane is a traffic lane, you need to wait for it to be clear before turning, and yes, you need to check your shoulder on roads with bike lanes.
Bike lanes aside, if they aren't checking their shoulder they could also easily hit a person approaching the crosswalk.

GP is just a shitty driver, is my takeaway.

generally it's the motorists who are dangerous to the cyclists... when's the last time someone in a car was injured by a bicycle?
Directly? Don't know that I have. But just a few days ago I saw someone that had to slam on their brakes to avoid hitting a cyclist that did not have right of way through an intersection, slide off the road into a tree. I don't know if they were injured physically, but the financial damage was probably not insignificant.
> Cyclists are just dangerous

Nope. The numbers of people killed or seriously injured in road collisions that don't involve motor vehicles are absolutely tiny. Motorists are dangerous, cyclists are not.

> Cyclists sometimes behave as though they are pedestrians and other times they behave as vehicles, depending on what is convenient.

And? Is that somehow bad? This seems to be a common motorist talking point, but I've never understood what it's supposed to imply.

> And? Is that somehow bad? This seems to be a common motorist talking point, but I've never understood what it's supposed to imply.

Yes, it can be very bad. Drivers not being predictable is a big cause of car crashes. I was always taught that when driving, don't be nice, be predictable. It's also a large part of defensive driving. A cyclist that is sometimes acting like a vehicle, and at other times as a pedestrian is not nearly as predictable.

It seems quite predictable to me. Just assume they could be acting as either!
Cyclists act like cyclists, and are more or less predictable when treated as such. Cyclists are not vehicles, and it doesn't make sense to insist they behave like vehicles. The theory of vehicular cycling was one of the worst things to happen to the development of a safe cycling community in America.

https://www.strongtowns.org/journal/2020/4/28/why-john-fores...

> Cyclists act like cyclists, and are more or less predictable when treated as such.

Except when they ignore stop signs and blow through an intersection when it's not their turn, causing a car that has the right of way and is already in the intersection to slam on their brakes to try to avoid killing the cyclist, resulting in the car losing traction due to the weather conditions and to slide into a tree. Saw it happen in front of my eyes just a few days ago.

Or when to avoid stopping behind a car that was already in the turn lane in front of them, they hop up on the sidewalk and then cut off the car via the sidewalk, nearly running down several pedestrians. That one was earlier this afternoon.

Cyclists and pedestrians are not the same, and should not be treated the same, or interchangeably. I agree that the way that infrastructure is set up right now is terrible for cyclists. But it is how things are right now, and ignoring that is silly. It's not at all that different from how having pedestrians and cyclists sharing the same roadway is also not the best of ideas.

But in addition, you know those signs they have up on the side of the road, the "Share the Road" ones? Sharing goes both ways.

Cyclists are no less predictable than motorists if you pay attention. I could give a litany of bad behaviour I've seen too, and the best available statistics say that motorists both break the law more often and cause vastly more deaths and serious injuries.

A shared space doesn't mean you're entitled to bringing an armoured, deadly machine into that space and expect others to take equal responsibility for the danger your machine is imposing.

> As a driver, it took me many years to get into the habit of shoulder checking when turning right from the right lane

If you weren't already doing it all along, that's kind of on you. It's literally on the driving test. I've been hit walking in a crosswalk by a driver who didn't check over their shoulder as I came up behind them while they were stopped. No injuries luckily.

I want to take a kinder view of your comment than some of the other replies currently, in that there's a kernel of truth in what you say. I would rephrase it though, in that it's not that cyclists are inherently dangerous, it's more that mixing modes of transport that have vastly varying capabilities is dangerous. Any time you have vehicles of vastly variable mass and capabilities sharing a road, it's inherently more dangerous than if they were to be separated.

That goes for cars and bikes, and cars and pedestrians, and bikes and pedestrians.

> I always have my turning signal but to cyclists it doesn’t mean much, they will always try to pass me on the right on the intersection

I suspect you aren't merging into the bike lane when turning right and leaving space for a cyclist to pass you on the right. I've seen many drivers make that mistake. As a cyclist I never pass cars on the right in this situation because drivers don't check.

You are supposed to merge into the bike lane before turning. It's in the DMV handbook. The painted bike lane becomes a dotted line close to the intersection for precisely that reason.

This varies state-by-state. In Oregon the bike lane is not a turning lane, and the locals will express their displeasure if you use it as such. We have bike boxes and lots of no-right-turn-on-red signs instead.
Cyclists are far from the only ones who don't stop at stop signs appropriately. Stand on a street corner sometime and count the cars that come to a full stop. I'd be shocked if you find more than 20% do. Which is all well and good as far as I'm concerned as long as people are paying attention and it doesn't cause an accident.

But if cars that take no physical effort of the driver to get moving again aren't expected to come to a full stop, it seems unfair to expect that of bikes. Of course if you blow through an intersection full speed without looking all bets are off and you probably get what you deserve, but I chafe at the bar being set at a "full stop or it was your fault" way of thinking, especially when the cyclist has so much more to lose.

The more important thing is yielding. I've very rarely seen a car fail to yield at a stop sign, but people on bikes or e-scooters do it all the time. They even hit peds sometimes.
> there are stop signs in all 4 directions

This is a complete aside, but woah, is this common in SF? They simply aren't used here where I am (roundabouts are used instead)

Like they're uncommon enough that theres a news article on it in a different state: https://www.news.com.au/technology/innovation/motoring/fourw...

A four way stop sign seems like an absolute downgrade compared to a roundabout, but thats my local bias showing.

Roundabouts are rare in the US. Four-way stops are far more common. If the authorities find a particular one to be too dangerous, they would normally install traffic lights rather than replace it with a roundabout.
Fascinating. I wonder what the cultural difference is that caused us to go in different directions on that?
I like roundabouts, but don't they require more space?
No, you can also have a mini roundabout, which is a white circle painted on the road. Maybe slightly raised but with no kerb so you can just drive over it. Yield to anybody in the junction and yield to the right (we drive on the left).

Very common in the UK instead of stop signs at intersections. Stop signs are only in rare places where a hedge or other environment prevents you from being able to see and yield to approaching traffic while approaching the junction. Even in that case there would never be a four way stop.

Interesting. We have a few of those in the US, but get this, they have stop signs too!
even it it were the case, it's not like American roads lack in space
They do in some places, like SF. Though even SF has more road than some Europe or Middle East cities.
Looking at the intersection [1], what a badly designed mess it is! You have 2 bike lanes disappearing into the intersection without any sort of protection.

Cars can be parked right up to the ped crossings, potentially obscuring what is happening. Looks like a death trap to me.

At a minimum, raising the crossings so that cars have to slow down, and having no parking zones in front the crossings would improve the situation by a lot.

Humans make mistakes all the time, intersections should be designed to accommodate that.

California recently made it illegal to park within 20 feet of a crosswalk:

https://www.dmv.ca.gov/portal/news-and-media/dmv-highlights-...

SF hasn't started enforcing the law yet, and I suspect that 99% of drivers don't know about the law.

They haven't started enforcing it because you can only issue warnings if people park close to the crosswalk until next year - specifically because most drivers don't know about the law.

And the law actually states that local authorities can come up with their own distance rules instead.

> They haven't started enforcing it because you can only issue warnings if people park close to the crosswalk until next year - specifically because most drivers don't know about the law.

OK, I see that now:

  (4) Prior to January 1, 2025, jurisdictions may only issue a warning, and shall not issue a citation, for a violation unless the violation occurs in an area marked using paint or a sign.
But honestly I often see cars stopped (waiting, not parked) in red zones and have never seen them get a ticket or even asked to move on.

> And the law actually states that local authorities can come up with their own distance rules instead.

I didn't know this!

  (B) Notwithstanding subparagraph (A), a local authority may establish a different distance if both of the following requirements are met:
  (i) A local authority establishes the different distance by ordinance that includes a finding that the different distance is justified by established traffic safety standards.
  (ii) A local authority has marked the different distance at the intersection using paint or a sign.
I wonder whether (n)(1)(B)(i) is, in practice, a high bar.
I doubt the bar is particularly high and the onus is on the city to create signs/paint curbs to indicate if it's longer or shorter.

As it stands, if there's a red curb or parking prohibition sign already next to a crosswalk, it dictates distance - whether longer or shorter - and there are a lot of intersections with those already that are much shorter than 20 feet - like where fire hydrants often are. If SF doesn't repaint/resign those, then nothing happens.

It's only for unpainted/unsigned areas where the 20 ft rule comes into place.

They don't have the "you're required to know the law, 15 days after it exists" law? Odd.
It's actually a legal principle in most countries. Hence my surprise. But keep flagging :)
Outside areas with dedicated parking enforcement patrols, do police actually issue tickets for parking within distance of thing?

I ask because, here in Indianapolis, on my heavily-trafficked mixed residential/commercial street, drivers routinely ignore both painted curbs and painted parallel parking space markers for days at a time and seem to be rarely, if ever, ticketed for doing so.

EU guy here.

Usually in european countries when there are stop signs, they only apply to smaller streets/roads that connect to larger prioritary roads/streets. If we want equal level of priority for all directions we either use, traffic lights, roundabouts were usually the one already engaged in the roundabout has priority over people connecting to it or use priority from your right (default priority in France for example unless specified).

Who gets priority in a 4 directions stop sign?

If Waymo is truly as much better than Cruise as the statistics claim, this is a perfect opportunity to release the full video of the incident. Most collisions are avoidable, but a few are the result of a perfect storm of conditions that would be difficult to navigate for even the most skilled human driver. To know whether the truck's occlusion of the cyclist is one of those cases requires the actual footage.
Yes, they definitely have full footage. I would appreciate seeing it.
> this is a perfect opportunity to release the full video of the incident

I hope they’ve released the full video to investigators, but they’re in a tight spot — SF city government is looking for reasons to come down harshly on the company, and trying to sway public opinion ahead of the city’s verdict won’t help.

Why wouldn't it help? I think entirely the opposite, if they believe that SF city government has political reasons to misinterpret the evidence, then putting the evidence to the general public can act as a check to the SF government, preventing them from any shenanigans asserting that the video shows something other than most members of the public saw there.
Only way that happens is if the cyclist signs a boatload of paperwork to waive his right to litigation.

And on top of that, I'm far less interested in the footage than I am the telemetry. What was the state of the gas and brake, what was the steering angle, how long was it from detection to action. Those things concretely answer the question of "would a human have done better or worse in this situation?", which is ultimately the only question that matters.

It would have to be provided if the cyclist sues Waymo and reaches discovery.

You absolutely cannot answer that question without looking at the video and considering how easy or hard it would have been for a human to detect (or suspect) the cyclist in that situation.

I don't think you can "absolutely" answer the question with the information that, at least could be, available. You can certainly form an opinion that's closer to agreeing with reality however, which is mostly what I'm interested in.
> I'm far less interested in the footage than I am the telemetry [...] how long was it from detection to action

It sounds like you're making a deeply unreasonable assumption that no human could have detected or anticipated the cyclist faster than the computer did.

Given the current state of the art, those times are frequently not the same, and the difference cannot be answered without seeing the human-consumable video footage of a prospective human driver.

I'm assuming nothing. I'm simply posing a question, not answering it.

It's your post that is nonsense, as it appears you've read about half of what I wrote before you replied.

Perhaps it's not what you intended in your mind, but it's what you happened to type out in ASCII.

In this quote, you are asserting that something is true::

> What was the state of the gas and brake, what was the steering angle, how long was it from detection to action. Those things concretely answer the question of "would a human have done better or worse in this situation?"

Unfortunately it is not true: "Those things" you just identified in "the telemetry" can not "concretely answer" the question of "would a human have done better."

In particular, that is because "done better" includes detecting the obstacle or risk sooner--not merely time between detection and braking. To answer that, the inputs that would have been available to a human must be scrutinized by other humans, which means the video is important.

Did I at any point say the video wasn't important? I don't recall doing so. I did assert that the telemetry was more interesting than the video, but the telemetry being more interesting than the video feed doesn't mean the video, itself, is not interesting. You missed that in favor of being pedantic, that says something about you, and if I thought it had any chance of helping, I'd tell you to take a long look in the mirror and wonder why you are the way you are.

That'll be my last reply though, I'm watching a youtube stream of a guy trying to get gentoo to boot off NTFS, it's not going well, but it is more interesting than providing detailed analysis of simple language that you've misunderstood.

Imagine an alternate universe where everything was cut short by: "Oops, yeah, video would be important for that case, I was focused on a different failure-mode."

> Did I at any point say the video wasn't important?

Sounds like Motte and Bailey time.

The expansive Bailey: "We don't need raw video to concretely answer whether the machine did better or worse than a human, the telemetry is sufficient."

The defensible Motte: "I never said the video was unimportant..."

> pedantic [...] detailed analysis

Step 1: Casually dismiss the other person as having not read your post.

Step 2: When they lay it out in detail, whine that they read your post too closely.

The issue that people have is you stated that you'd compare time from detection to action.

What most people want to compare is time from when the bicyclist could have reasonably been detected to action. This requires looking at the video frames to decide when we think a human would have figured it out.

If the footage is not released to the public I'm going to assume it makes Waymo look bad.
They did say that the Waymo only braked after the cyclist was 'fully visible'. They won't be releasing the footage on their own.
Yeah that was an interesting weasel word. It raised a lot of questions.
Based on actual experience driving and living in SF, I just assume any cyclist involved in an accident was ignoring the traffic laws and found out why they exist the hard way.
I agree it would be good to share video if possible, but Waymo cannot realistically expect that there will never be an accident where they look bad.

There are 43,000 US road deaths per year. If all driving was autonomous, even if autonomous driving was 100x safer than humans, that would still be 430 deaths per year.

And some of those accidents will be failures that a human would not make (sensor failure, bad software update, edge cases).

What you _can't_ do is what Cruise did and hide evidence from the public and regulators fearing that the truth would impact your business.

Seriously -- automated cars are going to kill a lot of people[0] yet by every objective measure that is a good thing. There's a cognitive dissonance here that needs to be overcome else society will pay to the tune of tens of thousands of lives per year.

[0]captured in multi-angle 4k, replete with gore and blood splatter. leaked to the press, compiled into tic Tok reaction videos, etc.

This is one of those things that should be legally required tbh.
Well, maybe. It should definitely be required that they turn any accident records over to regulators, other parties in the accident, and police. But to the public? Imagine if it were gruesome. I doubt I'd appreciate video of a family member violently dying going viral.
Any accident involving a self driving car is already reported to regulators (CA DMV and NHTSA). It’s required by law. These records end up in a public database.

What’s not public is the video footage. It’s still shown to the regulators when they want to examine, it’s just not publicly released.

What about the privacy of the bicyclist? What if it was his/her mistake and they don't want to be ridiculed by the entire world?
You can blur their face?
(comment deleted)
You can still be identified by things other than your face.
There is no expectation of privacy with what happens on a public road.

See all the dashcam videos on YouTube.

> There is no expectation of privacy with what happens on a public road.

There's a common misconception that there is not an expectation of privacy in public but this is not supported by the law. The notion does not help people but does help those that wish to surveil. Be careful with this claim.

The question isn't about the cyclist asserting a right to privacy, it's about whether it's a decent thing for Waymo to do regardless. There are more downsides than upsides (to the company) if they did do a public release of footage.
Counter: see all the blurring in Google Maps Streetview.

IIRC they were sued about identifying people and car plates.

They have no reason to release it to the public. They don’t want to set a precedent. They will show the video to the regulators (CA DMV) and if they’re not happy, they will take action. It’s regulation working as intended.
Public trust is a pretty good reason.
There’s enough to establish public trust with their voluntary release of safety data and regulators closely overseeing their operations.

Setting a precedent for releasing footage means fault is automatically assumed when they don’t voluntarily release it.

It’s a problem if they’re not even releasing it to the regulators, but that’s not happening here.

Not to mention that no matter how compelling the footage, people will argue who is at fault.
Yup. Also people using edited footage out of context for nefarious purposes. Really zero benefit for Waymo to release footage, only things to lose.
And that's exactly why regulators must compel them to release the footage immediately if they wish to continue operating on public roads.
They will release the footage to the regulators, likely without having to be asked.

The regulators don't want the footage released to the general public any more than Waymo does—the last thing they need is a bunch of armchair traffic accident investigators telling them how to do their jobs.

So what? People can argue about many things, that's not a valid reason against it.
It's not enough, because at least for me and a few others (e.g. the neighboring comment "If the footage is not released to the public I'm going to assume it makes Waymo look bad.") being able to judge the event personally can establish much more trust than anything they do with the regulators, because we also don't necessarily fully trust the regulators and their political motivation, and want to see if we would agree with the regulators for such major cases.
Unless you’re willing to watch millions of hours video of every Waymo vehicle driving and judge them in aggregate, watching a one-off incident will tell you nothing about their safety. At that point, you might as well trust their aggregate statistics reported to the regulators because they capture everything.

If you’re not an expert, it’s best to let the regulators and insurance adjusters do their job.

Your argument is much less effective at making me trust Waymo than the accident video could be.
Esp if one considers it’s the same argument cops make when trying to suppress incriminating police shooting footage.
Sounds like the same argument bad cops claim after questionable police shootings

Public trust requires building it first. As one of the first instances of a waymo crash, yes the public needs to see it. If after reading the footage in the first 99 crashes and in each time waymo’s assessment was valid, that’s when Waymo has public trust and can credibly not release every single video but only do it on a case by case basis.

How do you get to "bad cops" from here? Bad cops are "investigated" by their own units. So that analogy doesn't work.

Waymo is regulated by independent agencies (CA DMV and NHTSA). They are watching the videos and assessing if Waymo is telling the truth. Their permit is pulled if they get caught lying (like Cruise). How are you and thousands of SF residents more qualified than them? Why should I take your assessment more seriously than that of the regulators?

PR 101 is usually to say the bare minimum re bad press. And maybe release it later when it's out of the news cycle.
It’s a motivated audience in San Francisco. Data will not change their mind.
Good, they should be forced to set a precedent.
> They have no reason to release it to the public.

The public is allowing them to borrow govt-built roads to test their products and potentially endanger the public. That's more than enough reason for Waymo to be transparent here.

No, the regulators (who are indirectly appointed through the public) are allowing them to use govt-built roads to test their products. They don't have a direct obligation to you or any other citizen.

I'd like them to release the video, but just be clear what you want, and best not to act like it is required of them.

You are 100% correct.

Waymo reports to the DMV, they do not report to you or me.

The roads belong to taxpayers, not regulators. The regulators are supposed to work for us.

Anyway, I'm talking about a moral or PR obligation, not a legal one. Waymo is using roads that taxpayers pay for, and that raises the bar for transparency for them.

You would think so but no. Roads and highways belong to the State or Federal government (basically whoever built the damn thing).

States and the Federal government are managed by an Elected government and their appointees, and are empowered to levy taxes.

Taxpayers foot the bill, and some taxpayers are even citizens with the right to vote in elections.

The whole “X belongs to the taxpayer” is crap rhetoric you and many many many Americans were raised on, but which does not accurately convey anything about your relationship with the roads and highways you use. We pay for them, we elect the people who are charged with managing the entity that does own them and employs people to build and maintain them, but we do not own them.

Yeah, again. I'm not talking about the legal framework, I'm not poorly educated on this subject as you condescendingly claim, and nothing you wrote affects my point.

I'm saying that we pay for the roads, and the entities that legally own/maintain/control the roads are supposed to be under the control of our elected representatives. We own the roads in the sense that they are public spaces that we pay for.

There is a moral obligation to transparency when benefitting from public resources, whether or not there's a legal one.

> They have no reason to release it to the public.

I mean, if it reflects positively on them, they have huge reason; they want to put as much distance between their response and Cruise's as possible, and show that they're acting in good faith.

A large part of what killed Cruise was, well, either the cover-up or its employees' amazingly persistent internet connectivity problems, depending on how cynical you want to be.

The positive PR is so negligible it’s not worth it. This is an incident where no one was even injured.

If they want to put as much distance between themselves and Cruise, they just need to be transparent with the regulators and not play games with them.

Eh, if I want to be as upfront and "look how open we're being" as possible. They have a marginal basically-prototype product, in a limited market where a lot of people are already very annoyed about them, and the main competitor has just vanished in a puff of poor crisis management. They should really be leaning on demonstrating to the public that they're different.
This sounds like a bad idea. I doubt people will respond with proper context, especially given that it will still be lacking in information. We already see people here making assumptions without sufficient evidence. Anything with cars and cyclists is always heated and we just get a lot of biases.

I think it is better that we distinguish that this type of event does not actually inform us about the safety of driverless cars nor does it provide enough information to adequately update our positions in either direction. It is void of so much context that it is essentially just noise. These things are hard to measure and even harder to make accurate decisions on. In an extreme case, it is possible for driverless cars to be "better than humans" at driving in the notion of accidents per mile (even normalized) while also being "worse than humans" in the notion of striking cyclists or pedestrians. "Accidents per mile" marginalizes the type of accident, but this would be important information as to making effective policy about when and where a driverless car can deploy (e.g. on average fewer accidents but most miles are on the highways. If there's a high rate of failure in detecting children in suburban settings, I sure wouldn't want that car driving in residential areas. The nuance matters). I think it's fair to say that the vast majority of us here on HN have a poor concept as to what the actual nuanced data says here and personally I feel like a video would only further sensationalize the event. I would not be surprised if a video were released which showed that Waymo could have not performed any better (without x-ray vision or omniscience) yet it also be used to further cases against them. I'm sure most people would make an accurate and reasonable conclusion upon seeing the video, but I still don't have faith that that means it wouldn't end up being sensationalized.

> This sounds like a bad idea. I doubt people will respond with proper context, especially given that it will still be lacking in information.

Waymo has 360 degrees cameras. There's absolutely no lack of context if the video starts 2-3 minutes before the incident and stops when everything was sorted out at the scene. Bonus points if it has audio also.

The video would be cut to only show the most dramatic moment a minute after released, and it would be the shorter version to become popular.
For tabloids, yes, but the same happens with any other video of an accident. So it is not a reason not to be released.
The public are not entitled to that video. Regulators and engineers, sure, but to release it to the armchair uninformed public because of their morbid curiosity does nothing to advance safety engineering.
I wouldn’t be surprised if the cyclist blew through the stop sign as is incredibly common.
It's also arguably safer for the cyclist to do so. Bikes typically accelerate much slower than cars.
It can be safer, but it's definitely not safer to do this if you're right behind a big truck that blocks other cars from seeing you.

There's a right way to Idaho stop, and this ain't it.

Do waymos perhaps pass through behind a vehicle much faster/closer than a human driver? That would appear like one of those things that "computer accuracy" could do that humans would never try.

A cyclist confident to be able to keep up with the truck's acceleration might go not only for the physical slipstream, but also for the "traffic slipstream", remaining so close that he would never intersect paths with a regular driver. That would be breaking traffic rules, not arguing that, but it would not only be safe (-ish, truck might hit the brakes) but also not inconvenience any drivers who wouldn't pass behind the truck without leaving a sufficient gap anyways. Until a waymo shows up and ends that assumption (this is speculation, I don't know how waymos drive)

In any case, from a continental European perspective the American four-way stop just seems completely wrong, despite priority to the right being essentially the same when fully saturated.

Can you explain? That doesn't really make sense to me.
(comment deleted)
No, it's safer to follow the rules of the road. Stop at stop signs and red lights or risk winding up on someone's windshield without anyone's pity.
California has Idaho stops, so cyclists not stopping at Stop signs IS following the rules of the road (if the Cyclist did yield and just also didn't see the Waymo car).

Bicycles starting on the side of the road can ofter get side swiped because they're in car blind spots because they don't accelerate fast enough. Going faster makes them more visible for cars.

Even if that were legal in California, clearly in this case the cyclist did not check properly and should have fully stopped.

I must say, all of this doesn't help with the general perception of cyclists being extremely entitled with respect to ignoring traffic rules. Anecdotally, I see more cyclists breaking the rules (such as by riding on the sidewalk or pedestrian crossings or improper lane changes/turns) than not.

What an absolutely deranged comment to make.

Are you of the opinion that anyone going even ever so slightly over the speed limit deserves their fate if they happen to crash and get injured or killed?

Car drivers do after all break the rules of the road far more often than cyclists do, with further-reaching consequences.

This incident literally disproves your claim.
I said "can be" not "is always". Don't go there.
So the scenario (as described by waymo, surely with some spin):

"Driving through a 4 way intersection, while a large truck is also going through the intersection. As you go through, a biker quickly passes behind the truck with minimal time to react once in sightlines."

A human driver would take significantly longer to react, and could be deadly.

Waymo managed to hit the breaks before the collision, potentially leading to only minor scrapes. Feels much better than human would fare in a similar scenario.

What I hope Waymo learbx for this, as well applies as similar scenarios: never cross through these zones of high bike traffic when the obstruction from another vehicle prevents a wide enough view to brake before this zone.

>What I hope Waymo learbx for this, as well applies as similar scenarios: never cross through these zones of high bike traffic when the obstruction from another vehicle prevents a wide enough view to brake before this zone.

I hope it's as simple as that, and that regulators will understand just how little fine-tuning could yield substantial safety increases not possible with human drivers.

I hope regulators watch video from the vehicle and think, “damn I would not have been able to react that fast. Sure we can make these things even safer but it would be immoral to block waymo’s operations as it would certainly increase harm.”
> damn I would not have been able to react that fast.

i apply my own standard of driving to it: I wouldn't get in that position in the first place.

It seems to me that the best metric might be whether the average driver would get into that position or react faster if they did.
I don't know if i'd ever feel good enough to get in an autonomous car if they were just a bit better than the average driver... the average driver is not great.
Not only that, but fine-tuning is cumulative. Test situations can be created and tested against forever. Lessons can be learned and applied across the whole fleet.

This is radically different from sharing the roads with a bunch of Sunday drivers, some of which might be distracted or impaired.

Yes, it totally makes sense for bike commuters to be run over and sent to the hospital by robotic driverless vehicles while billionaire entrepreneurs refine the AI models powering them — it’s a beta test after all, you can’t actually expect it to work on public streets. And I bet those cyclists weren’t even paying their road tax.

The needs of the 95th percentile that the model was tuned for outweigh the needs of everyone else, who can’t even afford a basic RWD Tesla Model 3 (which is pathetic and the most pedestrian of EV options since I drive an EV GM Hummer and I post on Hacker News)

I think that line of reasoning would only apply if the driverless vehicles are not better than human drivers. That is to say, it's perfectly reasonable that bike commuters would die as the software is improved as long as less bike commuters are die than would without the driverless cars.

To be clear, I don't know that I necessarily think that driverless cars currently are better than human drivers. I'm just pointing out that the logic changes if they are.

Logic and morality are on two separate paths. IF the driverless car decides to kill your daughter because saving a van full of refugees was for the greater good, then it wouldn't be a question of what was "better," it would be a question of what was "righteous." In this hypothetical scenario, logically it would make sense to kill your daughter and apparently you're completely comfortable with amoral constructs making this decision on your behalf.

Fortunately we don't have to ponder such philosophical dilemmas while the current iteration of so-called "driverless" vehicles are `developmentally delayed` to put it lightly. But I guess a few bruised-up bike commuters are considered "acceptable loss" along the way to real progess (which is surely coming soon, surely)

We get run over with or without driverless cars, but driverless cars do it an awful lot less and will keep getting better at it.
Then by that logic the software engineers should be prosecuted for involuntary manslaughter when their beta test kills someone.
I don't follow your logic
> What I hope Waymo learbx for this, as well applies as similar scenarios: never cross through these zones of high bike traffic when the obstruction from another vehicle prevents a wide enough view to brake before this zone.

This might be fair, but at some point, if you are applying this consistent level of caution, there isn't going to be anywhere in the real world left to actually drive

Yes. I appreciate the political reasons for wanting zero accidents, but fewer, less deadly accidents than if a human were behind the wheel is what the goal really should be.
That’s such a low bar though. Zero is achievable.

Part of it is to slow cars down and take more cars off the road rather than changing who drives.

Invest in public transit, redesign problematic infrastructure, and create mixed use urban areas so people don’t feel the need to travel through a city.

A city should be a safe place. More deaths in a slower zone than on freeways is preposterous. I understand the reasons why this is true, but the deeper reasons for the reasons are that we gave up.

Fewer, less deadly automobiles is what the goal really should be.

> A city should be a safe place

Is that a fundamental attribute of a city?

Of course; that's why our ancestors first built walls around granaries.
I’ll go deeper still. It’s why we’re social animals. Trust is the foundation of secure relationships and secure relationships keep us safe. Cities wouldn’t exist if it were every man for themself.

Yeah, for sure I believe that cities, walls, friendships, food chains, economies, armies, language… this all rests on meeting the basic human needs of shelter (security from elements and hostile actors), food (security from starvation), community (security of a support network).

I’ll grant that this was a statement of a value I personally hold, an ethical axiom which I can’t convince you of. Fair.

Would you care to present a your own views? Or to dispute the reasoning that follows from my stated values?

If not, then we aren’t going to agree. I’m very much in favor of streets not being designed like the video game Frogger. Listen, I like snowboarding; adrenaline is a blast. But I don’t know why getting groceries has to be an adrenaline rush.

I’m making a joke. I’m coming into this debate with established opinions. But even if you’re not going to win me over, the floor is yours to persuade future readers that speed and carrying capacity are more important than safety. Or to argue that I’m presenting a false dichotomy.

What I don’t find acceptable is accepting the status quo just because it’s the status quo.

> This might be fair, but at some point, if you are applying this consistent level of caution, there isn't going to be anywhere in the real world left to actually drive

Not true. The Netherlands actually will redesign roads and intersections when this kind of thing happens; it will also actively seek rules for cars and cyclists that prevent visibility obfuscation. America just doesn’t believe in that, the only fix it can come up with is “drive better, cars.”

Let’s apply this same thing to humans. If a human engaged in this situation, no one would blink an eye.

SF had a “zero motor deaths” goal for 2024 and there were human drivers in protest that any changes made to save lives would be inconvenient (eg removing parking spots to increase visibility). The ease at which people will negotiate a human life for parking is horrifying. And likely speaks to how they drive.

We really should make driving much more cautious and undesirable. Any incident should result in serious penalties. In MA, if you’re <18, and you get a ticket, you automatically have your license suspended, and depending on severity, you may need to re-apply for a license, and start the testing and permitting process over. This really should be the adult process too.

If people are worried that loss of driving will disrupt their life, then all of society might slowly become less car dependent. This would have great effects on the environment, people would have shorter commutes, they’d probably be healthier. Cities would be more walkable, people would save money on the incredibly expense that is cars, and so much more.

(comment deleted)
This.

I've seen all of those walkable cities, green cities, etc... For the most part, I think that staying away from driving is a good idea. If we could have cities planned out so that anything would just be a few minutes walk away, that would solve so many problems.

A car-independent society would have many improvements. Even for medium distance travel, we could have trains and such.

What you're describing is exactly how a large part of Japanese society lives today. It's one of the main reasons I moved here. I don't need a car, I walk or cycle or take trains wherever I need to go, including to other cities.

Americans really don't want to live in this kind of society. They don't like walking that much, and they like the isolation and feeling of superiority they get by driving around in an expensive vehicle that signals their class, and they generally hate walking anyway.

> Americans really don't want to live in this kind of society.

What's crazy is I don't think this is true. I think Americans think they want a car-centric society, and we've structured so much of society to reduce our freedom to chose the alternative.

Where do Americans like to vacation? Walkable places. What cities and suburbs are regularly the most expensive and desirable in their area? Walkable ones. We built malls and commercial developments that provide walkability within a suburb. Literal Disney's fantasy main-street is just modeled on the walkable core of a suburb. Americans will say that cars give them freedom to go anywhere, then complain all the good places don't have enough parking.

Americans will tell you that college is the best time of their life, and it's largely because everyone was within walking distance to their social life, their job (classes), and their home. They eschew the commitment of vehicles, and they live close to others, and with less stuff.

Anyways, I guess I'm jealous you get to live in Japan, because I totally wish that America could invest in our transit like Japan has.

>Where do Americans like to vacation? Walkable places.

No, only some Americans vacation there. It's not like 80% of Americans all travel to European cities every year. In my observation, many Americans prefer to go to various US cities and rent cars, or to go to beach resorts, or spend their time on cruise ships drinking all day long.

>Americans will say that cars give them freedom to go anywhere, then complain all the good places don't have enough parking.

Right, this is one of the fundamental problems. Americans just don't understand that you can't have both.

>Anyways, I guess I'm jealous you get to live in Japan, because I totally wish that America could invest in our transit like Japan has.

Japan invested in transit because everything was already very dense. You can't just slap transit into a city like Houston and expect it to work out: you need high density to make it work. Living in Tokyo generally involves a LOT of walking (and stairs!); it's not like every destination is a block from a train station. It's why so many people own bicycles. Trains (and esp. subways) are extremely expensive to install and run and maintain, so you need very high ridership to make them work economically, and American cities outside of Manhattan just don't have that. You would need to change many things to get to Tokyo-level density; it'd be easier to just bulldoze the entire city and start over.

If you want to live in Japan and have tech skills, there's plenty of companies hiring here.

> No, only some Americans vacation there. It's not like 80% of Americans all travel to European cities every year. In my observation, many Americans prefer to go to various US cities and rent cars, or to go to beach resorts, or spend their time on cruise ships drinking all day long.

Of course it's not everyone, but it's more than just those that go to Europe. There are walkable pockets in America, and people go to them. Cruise ships are really mini walkable cities. Many beachy resort towns have a walkable commercial district. Disney is a giant walkable area, complete with a transit system.

I don't know all the history of Japan, of course, but I assume there some chicken-egg situation. If there is better transit, it'll encourage people to choose greater density (presuming it's legal to build). I would love the existing cities we have to (1) encourage dense, walkable buildings (eg. dense, w/ activated sidewalks) and (2) proactively build transit to suburban towns, to provide alternative transit options for commutes.

When I visited Japan, I noticed that beyond the typical subways of Tokyo, there are lots of regional trains that get to smaller cities outside of the megalopolis. I think that could be a great first step that America is equipped to do today. We have commuter rail in our biggest cities (eg. NYC), but we could continue to build that out to more places, to normalize using trains.

> If you want to live in Japan and have tech skills, there's plenty of companies hiring here.

Maybe I should learn Japanese first :) But a tempting proposition.

>I don't know all the history of Japan, of course, but I assume there some chicken-egg situation. If there is better transit, it'll encourage people to choose greater density

No, the history is exactly the same as those walkable European cities. The cities were built and grew (usually organically) long before the automobile was invented, or even before trains existed, back when people got around by walking and horse. Eventually, trains and subways were invented and installed in places. Cars came later, but by then the city was already there and quite large so there was no easy way to retrofit tons of parking spaces for everyone to drive everywhere. Subways weren't even built in Tokyo until well after the war, for instance; they're relatively recent. It's probably the same for most European cities.

American cities mostly grew after WWII and the popularization of the car, so they were designed for cars (outside very small downtown areas that predate the car, when the city had a small fraction of its later population).

Spending billions to build more train transit in American cities now doesn't work that well, because people still need cars to get from the train station to wherever they're going, because the density is so low. There's no real way to fix this, other than to change the policies to push for higher density, build a bunch of transit at taxpayer expense, and then wait a few decades for it to not be an economic black hole, all while voters are mad that they're paying SO much money for a transit system that has low ridership and continues to cost them dearly.

>(2) proactively build transit to suburban towns, to provide alternative transit options for commutes.

That only works well if 1) you build lots of parking at the suburban train stations for everyone to park in, and 2) everyone is generally going to a very small number of destinations (e.g. downtown). These days, though, the workplaces are usually in more suburban areas away from the city center.

>When I visited Japan, I noticed that beyond the typical subways of Tokyo, there are lots of regional trains that get to smaller cities outside of the megalopolis.

Yes, but those smaller cities themselves are generally walkable and dense too. They're not like American suburbs.

>We have commuter rail in our biggest cities (eg. NYC)

Right, because so many jobs are actually in NYC, so people need to commute there, and driving into (central) NYC is infeasible because there's no parking and the roads aren't that large. This is totally abnormal for American cities. NYC is extremely unusual. It's a very old city built mostly long before the car was invented, just like those European cities. The only other places in America like that are now just small downtown districts, such as the French Quarter in New Orleans, or the boarded-up downtown districts of dying rust belt cities like Gary, Indiana.

>Maybe I should learn Japanese first :) But a tempting proposition.

The companies recruiting foreigners usually have English as their working language. Learning some Japanese certainly helps, and makes it much easier to live daily life outside work here, but for those companies it's not a requirement.

It's not some perverse feeling of superiority or hatred of walking, but suburbs and cars are easier for families, especially large ones. The dense urban areas in the US tend to have more young and single people.
> When they became fully visible, our vehicle applied heavy braking but was not able to avoid the collision.

The "fully visible" part made me thinks humans can identify a bicycle and rider with just partial visibility, which means they would stop faster than the car.

Based on what? Humans run in to cyclists too and although I have know idea about Waymo's tech, in a research setting computers are better than humans at figuring out what objects are based on visual data.
If computers are so good at this, why am I (a human) asked to identify bicycles and motorcycles to train these computers when confronted with a captcha? A human needs far less training and can identify a person on a bike without ever seeing an actual bike. They can also infer what is likely to happen based on a lot of context clues. Even if an event doesn’t seem likely, I can still prepare. For example, if I see kids playing basketball in a driveway, I’m going to slow down, incase the ball bounces into the street and a kid takes off after it without looking. I don’t need to wait for the kid to be in the street to start reacting and prepare for different possibilities.
A computer doesn't need a multi million dollar marketing campaign convincing it not to text while driving or drive drunk.

>I don’t need to wait for the kid to be in the street to start reacting and prepare for different possibilities.

Neither does a computer.

> A computer doesn't need a multi million dollar marketing campaign convincing it not to text while driving or drive drunk.

A human doesn't get random bugs every week from OTA updates. The human mind is not a viable target for hackers. The risks of human drivers are individual. The risks of computer drivers are systemic and massive. One bad bug or hack could kill millions if self driving cars become ubiquitous.

>A human doesn't get random bugs every week from OTA updates.

What bugs are you referencing exactly? Humans have something called emotions that are far more variable than bugs in a safety critical system and you're exposed to thousands of different flavors every time you get on the road.

>The human mind is not a viable target for hackers.

But it is, and not even sophisticated ones at that. One lane change and a middle finger from a fellow driver can induce a murderous road rage.

>The risks of computer drivers are systemic and massive.

Hypothesis. Reality: 45,000 people die every year in the US from human drivers. That is systemic and massive.

You still don't get. All human problems are individual. Emotions in one person have zero impact on emotions in a driver two state away. Software problems are systemic. They change the entire system at once.

Your "just hypothesis" dismissal would carry a lot more weight if silicon valley hadn't been cranking out bug filled garbage for the last 20 years in their move fast and break things frenzy. Kyle Vogt was (in)famous for vaunting that culture at cruise so there's no argument AVs have somehow escaped the silicon valley rot. The tech industry need to stay far, far away from anything safety related

With the hacker comment, in fairness the weakest link in a lot of orgs is often the human one. Ignoring obvious stuff like phishing links, people can be disillusioned by their employer or their government through propaganda and other campaigns run by their adversaries. The westerners who supported ISIS, etc didn’t just do so in a vacuum out of the blue.
The computers don’t need you to do captchas anymore. The captchas are just solved problems being used to slow down bots and spammers these days.
You're linking to discussion of an article that explains bots are solving CAPTCHA and reCAPTCHA faster and more accurately than humans.

I don't understand what you are trying to say, but I don't think it aligns with the evidence you're providing.

You mentioned…

>The captchas are just solved problems being used to slow down bots and spammers these days.

If bot are solving these problems faster and more accurately than humans, it’s not really slowing down the bots and spammers anymore. That is also a solved problem.

Well, if it is solving CAPTCHA better and faster than humans, that is a useful signal. Maybe they monitor how often an IP address figures something out and if it gets too many right they +1 a suspicion counter. I dunno. Implementing the CAPTCHA solving bot also takes time and expertise; it'd filter out some low-ability spammers.
The captcha example isn't exactly fair, the images shown can be newly generatrd, repeated, or used as control images, and even if they are unclassifiable then you're not seeing the successes.

Without knowing the whole system there's too much hidden bias to claim the computer is more of less accurate than a commuter.

No doubt all of your excuses are at least partially true, however, at this point, literally after almost two decades of billions of people training these things to see bikes, it still needs a lot more work.
Recaptcha has not been used to train any neural network to detect anything in a very long time.

In fact, visual challenges like this are a mostly solved problem, and the real magic is the classification that happens behind the scenes.

How many years or decades did we spend answering them before it got to where it today?

I’m all for optimism, but these problems are clearly much harder than the futurists would like the public to believe. Elon said Teslas would be driving across the country to pick up their owners by 2018. 6 years later and what does it do, drive across a parking lot?

https://twitter.com/elonmusk/status/686279251293777920

Trains are also a solved problem, and seem like a much better solution to the problem. With rails, a vast majority of the complexity around driving goes away. They also remove traffic instead of keeping it the same or making it worse. Less traffic would likely mean fewer accidents, even if humans are still the ones driving. And batching transit together, with dozens of people in one vehicle is going to be far more energy efficient than everyone running their own vehicle. It also solves the issue of drunk driving, distracted driving, and bad drivers in general, as everyone is just a passenger.

So much money, time, talent, and energy has gone into this self driving stuff, and it seems like a massive misallocation of resources. They’re solving the wrong problem.

>if I see kids playing basketball in a driveway, I’m going to slow down, incase the ball bounces into the street and a kid takes off after it without looking

That's because you're a thoughtful, conscientious driver. A very large fraction of drivers are not, so society winds up with lots of dead kids. Humans are terrible drivers: some of them are OK, but too many are very bad, leading to catastrophic results, and because of this human drivers need to be eliminated. Alternatively, the society could become far stricter about which humans are allowed to drive, but that isn't feasible when the society has intentionally made it so that it's effectively impossible to survive without owning and driving a car.

Seeing a bike and inferring the vector of a bike are very different. A kid or tweaker on a bike needs more frequent updates than someone commuting or training.
> The "fully visible" part made me thinks humans can identify a bicycle and rider with just partial visibility, which means they would stop faster than the car.

From my experience as a driver and a bicyclist, I guarantee you that is not true, most driver won’t see you unless you are >60% visible.

Last year I caught this footage of a driver that hit a cyclist and they were fully visible. The police determined the driver technically wasn’t at fault because they had the right of way but humans drive incredibly unsafe.

https://youtu.be/uycFSrUI700?si=DPgNc_B5CNDctDyt

1) cyclist assumed they were safe to cross as there was a pedestrian 2) the driver didn’t slow down for the pedestrian in the road at all 3) driver was probably speeding 4) driver didn’t brake until very late, probably distracted 5) cyclist was 15 years old so probably not using enough caution in general

I honestly think a self driving car would have been going slow for the crossing pedestrian and this collision would have never happened (but I guess we can all just guess).

The question is, what’s better, occasional software glitches or human stupidity? I guess time and data will tell.

Not sure what the relevance of the pedestrian is because he far outside the path of travel for the car at the time he hit the bike.
most states require you to stop as long as a pedestrian is in the cross-walk (one of the many traffic rules that most drivers disregard).
Some states have a half rule. Or a rule that as long as the pedestrian hasn’t passed your car yet, you need to stop. I’m not even clear what my state (Washington) follows ATM:

> (1) The operator of an approaching vehicle shall stop and remain stopped to allow a pedestrian, bicycle, or personal delivery device to cross the roadway within an unmarked or marked crosswalk when the pedestrian, bicycle, or personal delivery device is upon or within one lane of the half of the roadway upon which the vehicle is traveling or onto which it is turning. For purposes of this section “half of the roadway” means all traffic lanes carrying traffic in one direction of travel, and includes the entire width of a one-way roadway.

I think they are trying to make the law more reasonable because there were police officers writing tickets for absurd stings. A person would step into the road and everyone would get tickets in the intersection. WA law seems rather convoluted but basically gives some room to use the road when the pedestrian is still out there. Probably more for those, I’m turning right at a red light and ped crossed the road, it’s clear to go now but someone is still technically in the crosswalk.

IMHO it's a slippery slope and vision of other cars can be obstructed by cars driving around pedestrians.

In general, people shouldn’t be doing 40mph within 10 feet of a pedestrian in the road (like they were in this case).

Anyway, I record this intersection because I see all kinds of carnage… 10 collisions in the past year next to a park. Human drivers are the worst

Our roads are pretty bad as well. True fix will fix the drivers, and the roads.
Even if a human sees the bike slightly sooner, the reaction time is so much slower that it's either a wash or the self driving car is likely still faster. Median braking reaction time for humans is ~500ms[1].

[1] https://pubmed.ncbi.nlm.nih.gov/26376036/

I can't read that article, but I suspect they're not including all the required foot movement there.

This study [1] shows ~2 seconds from gas lift to max brake force, when using right foot.

Eliminating the foot movement is why I left foot brake. I feel like I have some superpower with how fast I can react, compared to others. After all, we were taught to brake with our right foot out of tradition, not data!

Looks like the Waymo vehicle was turning after an all-way stop sign?

Is this a good representation with the blue car being the Waymo and the truck being the red car?

https://taylorkinglaw.com/wp-content/uploads/2019/09/4-Way-S...

Wonder why it was cutting so close to the large truck's back while accelerating during the turn that it couldn't see the cyclist till it was too late.

Them saying the car braked only after the cyclist was fully visible is additional cause for concern. Those are precious fractions of seconds. Doesn't Waymo use LIDAR? Shouldn't it detect the partial cyclist as a solid obstruction and start braking before the object recognition kicked in and recognized it as a cyclist? What if it was a trailer?

Yeah. Seems like good driving means "don't drive in to places you cannot see". If you are just accelerating after a stop sign, there is no reason to have such high speed and urgency when making the turn.
Right there can also easily be pedestrians in the crosswalk who are also occluded, though I guess with a bit more stopping distance (but then you may be blocking a lane that would otherwise be able to go).
Well, it sounds like the cyclist was doing the same while failing to stop or yield at a stop sign.
If the description is correct then the cyclist was going into the space that they could see in front of them, unlike the Waymo. Someone else said that stop signs are legally equivalent to yield signs for bicycles in California. They probably couldn't see the Waymo because it was occluded by the truck, so how could they yield to it.

This is why straight going traffic always has the right of way if the roads are similarly sized, and it's on the turning vehicle to stop and wait at the turn.

I would also hope that self driving cars are programmed to drive defensively and conservatively over trying to shave off a second or two of drive time.

>Someone else said that stop signs are legally equivalent to yield signs for bicycles in California.

California does not have the "Idaho Stop".

https://en.wikipedia.org/wiki/Idaho_stop

Presumably, Idaho does have the "Idaho stop", so driverless cars should be designed with that in mind, and operate as conservatively as possible to avoid crashes caused by other drivers or cyclists not perfectly obeying the rules.
Like how California leads the country on emission standards, you'd think the cars following the elevated CA emission standards across the country would also follow the Idaho standard too. Ignoring it is perilous... if a driver incorporates the Idaho Stop into their driving they will not be confused by bicyclists using the Idaho Stop. They might even be more prepared for other things like people running on the side of the road.

Drivers(Idaho included) by and far embrace the California Stop colloquialism if you ask me. The majority of traffic on roads is cars and the majority of traffic rolls through stop signs.

Reading that page, I learned that while California does not de jure have the Idaho Stop, it does de facto have the Idaho Stop. Waymo should account for this.

However I think that is irrelevant, depending on whether the description I heard is correct - it sounds like Waymo turned so quickly after a truck that it could not be certain its path would be clear. That to me seems like the real mistake.

Putting aside the debate on whether bicycles have to follow rules designed for cars, shouldn’t we still avoid accidents even if the bicyclist were unambiguously at fault?

But then that’s exactly why cars have stop signs. They trade high speed and carrying capacity against lethality.

(comment deleted)
Are we sure the Waymo was turning instead of the cyclist?

The only description is Waymo entered an intersection after a complete stop. “The cyclist was occluded by the truck and quickly followed behind it, crossing into the Waymo vehicle’s path.”

Yeah the ways I can interpret that are

1) The cyclist entered from a cross street going straight as soon as the truck partially cleared the intersection.

2) The cyclist was following behind the truck and then turned in front of the Waymo.

3) The cyclist was following behind the truck and the Waymo turned into it.

To me "crossing into the Waymo vehicle's path" is a pretty weasel-worded way to say (3), but it is technically true.

1) is hard to imagine given that neither of the streets are one-way (a crossing cyclist would not be occluded by the truck on the right and would not be able to go straight when the truck partially cleared the intersection from the left, unless they were traveling in the wrong lane.

2) doesn't make much sense to me... a cyclist with so little sense would have been hit by a car long ago.

Looking at streetview, I see bike lanes so there is also another possibility:

4) The cyclist was parallel to the truck on a bike lane, but the truck overtook the cyclist while in the intersection while the Waymo turned left after the truck cleared. This would be a similar situation as if there were pedestrians in the crosswalk.

edit: according to https://www.theverge.com/2024/2/7/24065063/waymo-driverless-... , the truck was turning? That opens up a number of other possibilities...

I feel like you are injecting facts with a lot of assumptions. How do we know a human driver would have taken longer? What if the human would have seen the bike 200 yards up the road 45 seconds ago, and since bikes don't disappear, waited a half second before proceeding into the intersection. Or what if a small portion of the bike was visible?

It could have been absolutely unavoidable but I don't think we know that now.

In my experience with motorcycling and bicycling as a primary mode of transport I'm happy if the human drivers attempt to stop at all
Cyclists are supposed to stop at stop signs, if not stop at least yield. At least in this case (if true), the cyclist followed the truck through a 4 way intersection (assuming it's a 4-way stop), that would put them in the wrong.

Hope waymo releases the footage.

There’s rules as written and then rules as followed — I’d much prefer a system that recognizes the rules that people tend to follow/bend/break — as a cyclist I too will often “convoy” with a bigger vehicle as it provides some additional protection most of the time (though obviously not here)

"Embarrassing" is a strange way of saying "potentially deadly" (for example, https://www.cbsnews.com/sanfrancisco/news/san-francisco-cycl... ).
> The felony conviction was the first of its kind in the nation involving a bicyclist.

The list of things that have killed one person in the last several hundred years is long. Everything is potentially deadly by that standard.

Here's a case mentioned in Law's Order:

"The plaintiff was about 14 years of age, and the defendant about 11 years of age. On the 20th day of February, 1889, they were sitting opposite to each other across an aisle in the high school of the village of Waukesha. The defendant reached across the aisle with his foot, and hit with his toe the shin of the right leg of the plaintiff. The touch was slight. ... In a few moments he felt a violent pain in that place, which caused him to cry out loudly. ... He will never recover the use of his limb."

(Vosburg v Putney, 80 Wis. 523, 50 N.W. 403 (1891))

It's the first felony conviction, not the first time a cyclist has killed someone.

Usually they get charged with a misdemeanor or not at all.

> rules as written/rules as followed

As a bicyclist in San Francisco, if I follow the rules as written, I cause traffic. Cars expect me to blow through four-way stop-sign intersections, and if I stop and wait for the cars, the drivers get confused & don't want to go (afraid of hitting me, I suspect).

In terms of right of way, the rules as followed seem to be pedestrian > bike > car.

I sometimes give way to bicyclists at four-way stops because I can't be sure they didn't get there before I did and I didn't see them because they're small.

And of course, if a vehicle, be it a bicyclist or car, enters an intersection when I have right-of-way, it's not like I'm going to start crossing and intentionally run into them.

Where bicyclists really risk their lives if they start assuming cars will give way to them is when they blow through two-way stops, especially at night or at one of the many intersections with poor visibility.

So are cars and yet it's common practice among drivers to simply slow down to 5-10 mph, declare that a "stop" and proceed into the intersection.
Note that there are bike lanes on the likely street where this occurred. The cyclist was not necessarily following the truck but could have been parallel (and overtaken).
I've been fairly impressed at Waymo's defensive driving skills, down to it being able to tell when someone turns around towards the road with an eye to cross, & the car slowing-down/giving a wider berth.

We will need to wait and see (i.e. footage) for more facts on this one, but I would caution thinking that Waymo's don't have object permanence capabilities.

(Usual disclaimer around 1st-hand experience etc etc)

Let's be honest, anyone making any type of conclusion based off the information in the article is just giving in to their biases. None of us know enough to actually have any serious opinion on this specific collision.
I'm drawing the conclusion that this is a non-issue, or would be if autonomous vehicles hadn't got to be so political over the last year in San Fransisco. There are many people out for blood, they want a follow-up to the Cruise scandal.

One fact of the matter is that the cyclist wasn't seriously hurt, and Waymo has had many minor contact events in its 10 million+ miles of driving on public roads. We're hearing about this event because politics.

You are just proving my point. You are pro-autonomous vehicle so you are interpreting the few facts we know in way that benefits your side of the debate.

Referencing the cyclist not being seriously hurt is the most obvious example. It doesn't take much for a car to seriously injure a cyclist. It often just comes down to luck of the cyclists physical position and where they fall. Onto the hood of the car is safest, but they could have easily been caught under the vehicle, pushed into other traffic, or dangerously thrown down to the pavement. A cyclist walking away from this collision doesn't necessarily mean the next time a Waymo hits a cyclist will be just as safe. If there is some fault in the system that increases the odds of it hitting a cyclist (something that is impossible for us to know) it would be only a matter of time until an unlucky cyclist gets seriously hurt.

I'm not pro-autonomous vehicles. Under the hypothesis that they worked well enough that they proliferated widely and people came to rely on them, they would be the most enshittifiable service ever.

Also I ride a bicycle everywhere, I don't own a car. I've had many crashes while cycling, a handful of which involved another moving vehicle.

Speed is a good predictor of how much harm a moving vehicle can cause to a cyclist or pedestrian, and given that the Waymo was turning left off a 4-way stop, it couldn't have been going that fast, and even if it was, the waymo stopped soon enough to avoid doing serious damage. Maybe the cyclist veered into the Waymo, we don't know. Maybe we'll get video and then we can really pick it apart.

There is a battle going on right now between the Governor of California and SF city council over the city's inability to regulate the existence of autonomous vehicles on their streets after the fast proliferation of Cruise's AVs led to all kinds of traffic snarls and general irritation amongst the public.

Cruise has been operating in SF since 2019 and has had many incidents more severe than the one we're discussing now, but they got little attention because it wasn't so political then. Nowdays SF is looking for any excuse they can find to get AVs out of their city.

In legal terms I doubt the city will find what they need with this incident. With regards to public sentiment, the headline "Waymo hits cyclist in SF" is about as much as most people will read, and the details of the crash don't matter.

>I'm not pro-autonomous vehicles.

Maybe not, but you are clearly coming from an anti-anti-autonomous vehicle stance. That likely plays into why you are downplaying this collision despite admitting "we don't know" basic details about what happened here. You are able to recognize that this issue is politicized, but like everyone you are considering your own political bias as the neutral position when in actuality the neutral position here is to wait until we have more details on what actually happened.

I think at the very least we can interpret the situation as car hits cyclist in a blind spot and the cyclist was not seriously injured. Sources say there were 49,000 vehicle-cyclist injuries and 846 fatalities [1] and there were 3.2 trillion vehicle miles traveled [2] in 2019. So my math comes to around .015 injuries and .00003 fatalities per 1 million vehicle miles traveled. Waymo’s traveled 20 millions miles by 2020, so more by now but Im not finding a more recent number. This is the first time I’ve heard of a Waymo-cyclist injury (maybe it’s not; I’m not able to google around this new headline) and would put their injury rate at .05 per million miles significantly higher than the other statistic but to get away with minor scratches is nonnegligible since it’s easy for injuries to be worse. At 20 million miles Waymos this rate doesn’t make them look good. I want to be optimistic about their injury rate getting better as they program around blind spots safer.

[1]https://crashstats.nhtsa.dot.gov/Api/Public/ViewPublication/...

[2]https://crashstats.nhtsa.dot.gov/Api/Public/ViewPublication/...

This is the same type of math that Tesla uses to suggest that their Autopilot is safer than humans, but the problem with this approach is that not all miles driven are equal. I guarantee that the injury rate per mile is much higher on the road in which this collision took place than the 0.015 national average. There are obviously roads in which collisions with cyclists are incredibly rare like interstate highways in which a cyclist even using the road is rare. That means there needs to be roads which greatly exceed the national average and those are often city streets with heavy cyclist traffic like this one where the collision occurred.
> We're hearing about this event because politics.

I think reporting on integrating autonomous driving into roads is a news worthy subject even outside of the agenda of a particular publisher. The good things are reported for autonomous driving as well. I don't live in SF but know that Waymo and Cruise both had fully autonomous vehicles in SF.

Having access to a comprehensive database of incidents and near misses would be informative. A single incident where only incomplete information is available doesn't tell us much.
> Having access to a comprehensive database of incidents and near misses would be informative. A single incident where only incomplete information is available doesn't tell us much.

Agreed!

I wasn't commenting from a safety perspective, but from a news perspective. Recently Cruise has had regulatory action taken against them from the California Department of Motor Vehicles due to an autonomous vehicle accident. Waymo, another company working on autonomous vehicles also has an accident! Sounds news worthy to me.

Of course reporting on a crash will always have some negative connotation for Waymo, and I hope the regulators look at more than individual incidents to evaluate the safety of Waymo's autonomous vehicles. I did learn that Waymo recently had an accident in a time period of scrutiny for autonomous vehicles as they further integrate into roads.

When Waymo was known as the Google Self-Driving car project they were cavalier about safety, but became much more conservative after spinning out as Waymo under John Krafcik in 2017.

Waymo has not had any serious incidents and these days it seems they're doing what they can to remain low-key and avoid attracting negative attention to themselves. Like you said, when Cruise, Uber or Tesla behave recklessly, it can't help but bode poorly upon Waymo in the eyes of the public.

We can't directly compare what these companies have going on under the hood because it's all quite proprietary. Waymo nonetheless has been chipping away at the problem for longer and with more resources at their disposal than any competitor. Waymo's 'Driver' is far and away the most experienced. While I'm fully confident making that claim, there's no easy way to measure it or make an emprirical comparison to other drivers.

If you want to play this game and you aren't very experienced, you can fake it by being reckless. You can make it seem to investors that you're better than you are by putting hundreds of vehicles on the road. Investors want results. You have to be able to point to a line on a graph that goes up and to the right and say "look at all these new benchmarks we hit! More cars! More miles!"

Waymo is effectively patronized and will run at a loss for as long as they need to without any pressure to fake it until they either make it or break it. It's Larry and Sergey's pet project. It's the one they won't let go of. A single scandal can really mess things up.

This feels like the "no vehicles in the park" all over again.[0] We're all naturally inclined to have assumptions, but I think many are not aware of this. I think all have the capacity, just not the habit.

What we do know is that this incident will be analyzed with the level of attention we would give to a plane crash. If there was any way the incident could have been avoided, the engineers will probably figure it out. It’s likely that software will be updated to implement a fix as well, and this type of accident will become much less likely across Waymo’s entire fleet. That seems like a really good result.
Only the driving software will be updated, the intersection will not be redesigned to reduce the severity of driver mistakes. It’s not the best outcome, ideally someone will analyze the case and produce the changes that needed to made to the driving software, the intersection, and biking behavior (aka the Dutch approach).
Fair, but then again, this would be taking drastic measures for a single data point. A full redesign would be quite a stretch for a single accident and nearly impossible to scale. The least you'd need to do is check for a pattern of accidents.
Yet that’s exactly what the Dutch do:

https://www.bicyclelaw.com/after-every-crash-in-netherlands-...

> In the Netherlands, accidents like these are followed by intense investigations, street redesign, and criminal prosecution on a level wholly different from Boston, where a slew of bike fatalities in recent years have prompted modest on-street changes and police crackdowns on bicyclists running red lights. But there have been few street design overhauls and no criminal convictions of motorists in those fatal accidents.

I’m pretty sure there is an HN discussion on this article somewhere.

Ah, the highest level of scrutiny is limited to and mandatory for fatalities, which makes sense.

(comment deleted)
Journalists swarm all over it. Waymo engineers will take their learnings. But honest question: is there an official, scrutinous authority also coming into this that would be able to hold Waymo to account? Maybe like the NTSB?
The thing is, human drivers do not and will never have such scrutiny. In this case, there is some hope that it will happen before these cars are widely deployed, even if said authority is the court of public opinion.
As a cyclist, I'm invisible to drivers quite often even when I'm not hiding behind a truck. Many drivers also immediately forget you after overtaking you just seconds ago and attempt a right-hook. It is of course possible that a human's advanced reasoning could have avoided the situation as described, but imo that would've been sheer luck or a very unusual driver.
Waymo and Truck in intersection both heading in opposite directions. I dont get where the bike was. It says behind the truck. So did bike run the stop sign and cross into waymos lane because that is way it sounds. Article doesnt state who's at fault.
Yeah, my reading was that the bike ran the stop sign and then attempted to make a left turn in front of the Waymo as it was going straight through the intersection.
My reading was that the Waymo was turning left. Remember, the description is from Waymo's PR, so that's why it's vague on purpose and needs to be taken with a grain of salt. According to another comment bikes can treat stop signs as yield signs in California. If the bike illegally ran a stop sign I would think Waymo would say or imply that.
I agree that there's still lots of ambiguity and Waymo's PR comment provides limited and one-sided detail. I stand by my previous comment as the most likely course of events, but we won't know for sure until video is released.

The comment that claims bikes can treat stop signs as yield signs in California is incorrect. From the CA DMV website [0]:

> Bicyclists must obey STOP signs and red signal lights, and follow basic right-of-way rules.

There was an attempt to change this a few years ago, but it didn't pass.

[0] https://www.dmv.ca.gov/portal/driver-education-and-safety/ed...

There was a bill to make something like this legal, but it was vetoed by the governor.

Even if it had passed, it wouldn't have changed anything about this situation. Because there was other traffic in the intersection, the bicyclist would have had to yield and stop before entering the intersection.

I think the most critical bits are left out here: “The cyclist was occluded by the truck and quickly followed behind it, crossing into the Waymo vehicle’s path.

Was the Waymo car turning or was the cyclist? Because if the cyclist swerved into oncoming traffic there’s likely little any driver could do, but if the waymo car was ignoring the possibility that a cyclist was behind the truck that seems like a significant safety issue.

I feel like Waymo would have said something if it was the former, no?

Since there's a bike lane on 17th street, it's possible that the cyclist entered the intersection parallel to the truck on the bike lane but the truck overtook it. It's even possible that the cyclist was in the crosswalk for some reason...

edit: according to https://www.theverge.com/2024/2/7/24065063/waymo-driverless-... the truck was turning?

Agree with sibling. You are speaking out of turn in that you have no idea how long a human would take to react, as we don't know the situation completely enough from this article.

That said, my takeaway is that the cyclist likely ran their stop sign. This is a very common accident situation even between cars, where the view is obstructed and the at-fault driver imagines that their path is clear. It seems very likely that the cyclist did a similar kind of thing, but with the additional aspect of ignoring the traffic control.

Since I'm here: brakes not breaks.

Waymo probably has cameras from every angle here, so it seems kind of odd that we have to rely on a textual description.
Privacy concerns mean that Waymo has a strong reason not to release video to us, the general public.

My guess is the most likely two routes you get video is either there's a lawsuit and so it's evidence or a government agency insists on having video and that gets either deliberately released or leaked to excited local TV news. In both those cases Waymo can say they had no choice, even if it's good for them.

I was hit while riding a bike in a situation that sounds similar: I was biking behind a car. A driver headed in the opposite direction turned left and hit me. I was difficult for the turning driver to see because I was obscured by the vehicle I was following. The description is totally plausible. It also sounds like the biker may have ignored the stop sign.
This is a situation I'm exceedingly careful about on bikes and motorbikes. I'll make eye contact with drivers and stand on the pedals/pegs to make sure I'm visible.

Most of the time, German drivers have good situational awareness. I just won't bet my life on it.

the cyclist left the scene “reporting only minor scratches.”

I'd never considered it before, but perhaps the endgame is humans getting used to automated taxis like potholes, animals, nails and other road hazards ? And then learning to judge the risk and accepting occasional small crashes like this.

/s ?

Did you just ask if the endgame is humans getting used to cars crashing into them?

Thanks for the chuckle.

Accepting occasional small crashes? Is this not already the status quo?
The status quo is accepting cyclists getting mowed down by human drivers by the thousands every year
As a biker on the road, yes, you absolutely do consider that the status quo. Otherwise you stand a good chance of joining that statistic. Cars do a lot more damage to you than you do to them.

Which implies nothing about any ideal state, either practically or legally. But it is an accurate description of the real world in many areas, and therefore a reasonable expectation when your life is on the line.

---

On a more technical level, legally and practically, the acceptable number of accidents is essentially never zero. That would imply absurd costs involved in prevention. Everyone wants it to be lower of course, but humans do not have infinite value in policy decisions.

The number pedestrians injured in the us by cars annually is around 60k. We're already pretty used to it. So yes, if automated cars reduce that to say 6k a year, that's still a win. As would be 30k, but lower severity injuries.
My guess is that the cyclist has really had minor scratches and decided that his time is worth more than waiting and filling in a police report.
As a pedestrian, I've been struck (once) by non-automated vehicles and yes, walked away on my own and that was that. We do already accept this kind of risk and you're just unfairly picking on AVs with that comment. Bicyclists accept huge risk, period. Simple things like people parked and opening the car door without looking, right into a cyclist, happen all the time. I bet every single day.
I would love to hear some stats on how many car/bike collisions happen every day in SF.
Prior to the pandemic an average of 1.4 bike accidents per day - https://www.mjqlaw.com/san-francisco-2022-bicycle-accident-s...
I don't know either but I do know that this collision has already got infinity times more press coverage and police attention than that time a wrong-way driver hit me on Howard and fled the scene. It's a problem with the whole AV discourse.
I can name two times in the last five years where, biking, I had a worse encounter than described (though I reserve judgment of fault until more details come out). Including one that required hospitalization, where the human driver decided to drive away.

The frustrating bit about AV discourse is that AVs are held against the standard of a perfect driver. Which I don't actually object to--all drivers should be compared to perfection. But it's enraging when people do so for AVs without comparing against human drivers, which, as everyone should know, fall far short of perfection. And with AVs we have the capability to iteratively improve them toward perfection, while there's no way to do the same with humans.

or maybe, Cyclist Hits Waymo
>Waymo personnel called police.

well at least the industry has learned something from the cruise incident.

> Waymo personnel called police. The company said the cyclist left the scene “reporting only minor scratches.” There was one passenger in the car and they were not injured, according to the company.

Full paragraph. Interesting that the cyclist left? If they are determined to be at fault, then I assume that’s gonna be bad for them?

> Officers rushed to the scene and found the cyclist with non-life-threatening injuries.

He left after the police arrived and assessed the situation.

As a cyclist I can't wait for these things to get more drivers off the streets. They're way safer than the average Californian.
> CITIZEN, you have been struck by an autonomous vehicle! I have reported the impact data to help us improve our platform. Thank you for your feedback.
Please collect your $25 participation gift card from the slot in the rear tailgate.
Sooo, is that picture from the incident?

Edit: The logo on the steering wheel is Jaguar.. That's a bullshit image right?

Double Edit:

> SFPD said the collision is under investigation and did not provide details on what caused the cyclist and autonomous vehicle to collide

So we don't even know who hit who lol. "Cyclist and Waymo Collide" sounds more accurate yeah?

>the logo on the steering wheel is jaguar. that's a bullshit image, right?

waymo has a whole bunch of Jaguar I-Pace SUVs. https://waymo.com/blog/2018/03/meet-our-newest-self-driving-...

It's a getty image. they're usually pretty good about disclosing whether an image is a real image or a composite.

Okay, so it's a real image but not of the incident?

Edit: I still have my suspicions it's not even a real image but a composite, getty or not. The shadows from the cyclist don't match that from the cars.

the caption says it's a file photo from november 2023...
So 100% not of the incident and that's journalism in 2024? I also suspect it's a composite.
I wonder if short range radar or sonar can help tell if there's something behind a large truck with the wave or sound reflections. If bats can do it, why can't computers?
It's uhclear from the description whether the cyclist was going straight in the same direction as the truck and the Waymo turned into the cyclist, or the cyclist was traveling across the direction of the truck and the Waymo.
Waymo certainly has the video of the collision. Just shows it!
"S.F. Supervisor Shamann Walton responded to the news of the collision on social media, saying, “So much for safety.”"

Why the snark? It seems it was a hard call, something that a human driver would not have caught and potentially caused a deadlier accident. As I see it there wasn't an investigation from the cyclists p.o.v.

The citizens of SF expect their elected officials to put on a good show.

Running the city well is too boring. Here's an article with the same supervisor threatening the sheriff's deputy running the metal detector in city hall: https://abc7news.com/shamann-walton-racial-slurs-sf-board-of...

To be fair all the supervisors and other electeds are clowns - nothing remarkable about Walton.

I'm disappointed in all the folks immediately blaming the cyclist without further information, and I'm similarly disappointed in all the folks blaming Waymo for the same reason.

But, unless they somehow have extra information we're not privy to, I'm much more disappointed in the S.F. Supervisor quoted in the article, Shamann Walton, for immediately going online to say "so much for safety." Us internet weenies are always going to have our hot takes, but someone in charge of the city has a responsibility to at least try to be better.

[flagged]
I think more impressively, even in this seemingly worst case scenario where everything lined up as poorly as it could have, the car was still able to react quite aggressively and the situation ended only with minor scratches it seems?

Honestly, if anything, this is probably proof that self-driving is the future, as I would bet any human would've most definitely done much worse in the same scenario.

I wonder if a human driver would have (for better or worse) swerved to avoid hitting the cyclist. That is, the Waymo might be programmed to only execute certain types of evasive maneuvers, whereas a human would instinctively do other things as well. Of course, if there were someone in the vehicle's blind spot, it's possible this would have resulted in a worse accident, since there would have been no time for a human driver to double check.
In a recent accident that happened in my country, a human driver swerved to avoid a cyclist that was quickly switching lanes without signaling in order to cross from one side to another. The swerving car went over the sidewalk and killed a pedestrian. You should draw your own conclusions.
This is my pet peeve with people being so sure online about their abilities of avoiding things on the road. Yeah, maybe you could avoid it with your super human reflexes, but there physically no way you could check that side of your car, register what's there, decide whether you can move that way and then did it. The kneejerk avoidance reaction may be extremely dangerous on its own.

(Also in Oz, rolling your car when you try to swerve to avoid a kangaroo is so common that you're normally taught to just break instead)

I swerved into another lane to avoid another car cutting me off during rush hour once. It all happened so fast, and I will always remember how incredibly lucky I was that no one was in the lane I moved into.
Do people really not mentally track the vehicles around them? I remember in driver’s ed even before we were behind the wheel to have “exit strategies” for situations exactly like this. Cars don’t just appear magically next to you.
> Cars don’t just appear magically next to you.

They don't, but: 1. Your perception is not perfect. 2. A truck passing you means there was a blind spot and you have no idea what was there. 3. There are areas with many lanes merging / splitting, where it takes most of your attention to know where you're going; little left to track everything around.

Tracking your surrounding is great. Accepting that you're going to make mistakes, adjusting for that and also allowing assistive tech is even better.

People try to, but are imperfect at doing so. For example, most people do not closely track what is happening 2 lanes away. But someone can move from your blind spot 2 lanes away into your blind spot right next to you.

Also, if something potentially dangerous/important is happening to your left, you will focus your attention there and not be aware of things happening to your right, even if you normally would have seen those things had you been looking straight ahead.

I try to know what is going on around me, for the reason you describe (exit strategies), but I'm aware that sometimes I simply do not know what is to my left — and would not want to swerve there.

Having seen friends driving Teslas, I can see how the surround-view could be useful for situations like this. However, I have also seen that cars appear/vanish for no reason, and it is clearly not reliable at this point.

Broadly speaking (and this is a very broad brush, details may differ), autonomous vehicles will resolve collision avoidance by doing something legal.

Swerving is not legal and it's not legal because you might hit something you can't see. On the other hand, an autonomous vehicle maintains perpetual 360° situational awareness so it already knows whether it's safe to swerve.

Can you provide a source that swerving to prevent a collision is not legal?
> Swerving is not legal and it's not legal because you might hit something you can't see.

If I'm driving down the road and someone pushes a kid in front of my car, I'm very likely to swerve, even if I'm not 100% sure if there is someone next to me. If I hit a car next to me and cause damage/injure people, there is a good chance that a jury would find in my favor because a "reasonable person" (the relevant legal standard in a civil case) would seek to avoid the certain death of a faultless child, even if it means a chance of injury to passengers in a vehicle that might be nearby. I wouldn't swerve if I thought a bicyclist were there, but I would likely swerve into a vehicle, which affords occupants significant protection.

And I certainly would not be found guilty of a crime ("beyond a reasonable doubt", the standard in a criminal trial) because it is not criminally negligent to swerve when faced with the certainty of killing a child. Under the "defense of self/others" doctrine, you can do many things that would normally be illegal, if you are doing them to prevent the imminent death of yourself or someone else. (These analyses are not super detailed, but IAAL.)

AVs aren't doing near enough calculus to make a decision like that; they have obstacles and they avoid them. Their avoidance can allow for lane departure (that 360 situational awareness is handy), but they aren't going to solve a trolley problem in realtime if boxed in.

The thing is... Neither are people. A kid darts out on front of you and you won't have time to make a conscious decision. The maneuver you make will be too fast for rational thought, and your brain will explain to itself why it did that later.

... Incidentally, this is one of the things that scares me about human drivers. Put a human on the stand to testify and most will say they never saw that kid, no matter what physical process happened to their eyes and neurons. I think most even actually believe it.

In any case, I'm glad that in this incident they'll be able to do a full NHTSA workup, pull logs, and reprogram the machine to avoid an accident like this in the future. Can't do that to a human driver.

Thare's a, probably not very obvious, situation when human could have no such accident in the same scenario. At all. Preventing an accident does not leave any trace. No one knows about the scenario if there's no accident.

How many similar (and others) accidents are being prevented by human drivers daily, and no one knows about them, at all? We just don't know.

That's why I take any stats of "human vs AI" driving with a grain of salt.

We can compare this statistically by looking at accidents per 1,000,000 miles driven of autonomous cars vs humans. Over long mileage, the rate of prevented accidents shows up in the data as a lower overall accident rate.

I don't have the stats at hand but Waymo does great on this stat.

Now, that's not to say that Waymo would avoid any specific accident better than a human. But from a public health standpoint, that's not really the right way to think about it anyways.

IMO these are a slightly fake stat. You're comparing to overall stats, that include the drunk, the high, the sleep deprived, and the crazy wild aggressive wreckless.

If you compare to my mother driving, the injuries per mile are higher in autonomous.

You can argue that I'm making an unfair distinction since those people exist, but I'd say the people driving under those conditions are commiting a crime and shouldn't be counted the same.

You're making a classic is-ought fallacy here. Drunk, high, sleep deprived or "crazy wild aggressive reckless" human drivers ought not to exist, but they do, and thus it's absolutely fair to compared autonomous drivers against them.
If GP's mother switches from driving for herself to having Waymo drive for her, her risk of injury will increase. Therefore, if her goal is to avoid injury, it would be counterproductive for her to make that switch. That conclusion does not require any is-ought fallacy.
Exactly. I know that my odds are different from the average.
So are you one of the 88% who know they are better than average, or one of the 12% who are worse?

https://www.smithlawco.com/blog/2017/december/do-most-driver...

>Obviously, not everyone can be above average. Exactly half of all drivers have to be in the bottom half when it comes to driving skills and safety.

This page is confused about the difference between mean and median. The 88% of drivers who think they are above average are not necessarily correct, but there would be nothing logically inconsistent about them being correct.

(comment deleted)
This has nothing to do with being "a better driver" than average. If you simply don't drive while intoxicated, extremely tired, or distracted with your gadgets, you're already beating the average when it comes to collisions and injuries.
> If you simply don't drive while intoxicated, extremely tired, or distracted with your gadgets, you're already beating the average when it comes to collisions and injuries.

It still does not make you a good driver. I've personally been in situations where I'm on the right lane, going slightly below the speed limit, when the vehicle (usually a pickup truck) passes me from the shoulder on the right, often blaring it's horns in disapproval as if they were on their way to save lives.

> Rules for Using the Shoulder. The laws for using a shoulder vary in each state, but it is illegal in all states to use the shoulder to bypass traffic or to pass another driver.

I can't wait to make it illegal for humans to drive on public roads.

It's mostly that. I don't think I'm more skilled or something. Also, using a smartphone while driving is illegal, but somehow using a 17" touchscreen that mirrors your smartphone and shows incoming texts is OK and common in newer cars.
Being better than average is easy because the average is dragged down by people who drive drunk/tired/etc. An average safety robocar would be a downgrade for most responsible people.
Yeah, I have 0 accidents, so nobody is going to convince me the AI is safer. Meanwhile my car's ESC has tried to send me off a cliff before.
That may be true, but I expect there's no scalable way to assess drivers for GGP mother-ness. So for public policy purposes we should encourage and allow self driving. And possibly even ban manual driving if we can't distinguish GGP mothers from poor drivers.
All self driving > Reckless drivers only self-driving > current situation > small random population only self-driving > GGPs-mom-likes only self-driving.

Unfortunately, identifying people like GGP's mother and excluding them from requirement for self-driving is prohibitively expensive (and icky in all kinds of ways), and so would be predicting reckless driving behavior (approximately every driver is reckless at some point anyway, GGP's mom included). So it's all self-driving or no self-driving, and all self-driving is strictly better for all of us, even if GGP's mom has to briefly accept slightly elevated risk.

> identifying people like GGP's mother and excluding them from requirement for self-driving is prohibitively expensive (and icky in all kinds of ways)

Not sure I follow the thinking here. We already have ability tests in driver's license exams.

Yes, and every mad or reckless driver passed them with flying colors, kind of by definition, otherwise we'd be talking about drivers illegally operating road vehicles. Approximately all traffic accidents involving drivers is involving drivers with valid license, who passed ability tests.
Those tests are dangerously insufficient to keep unsafe drivers off the road.
If your mother is a decent driver, then almost all the danger she faces while driving comes from other people being shitty.
In no possible future would we see an immediate change from human drivers to 100% self-driving, so self-driving ought to co-exist with human drivers, both the better than average, and the drunk ones.

I’m absolutely not convinced that an AI would fair better at handling a drunk driver’s driving style compared to a competent human. The statistics help AI due to them being good at handling monotony, but that doesn’t necessarily translate to safety in complex situations.

In a few places, driving too passively (as AI cars seem to do) will cause aggressive drivers to create dangerous situations for you. They don't want to be stuck behind someone who's letting people in. I also wonder if the AI cars go the speed limit on freeways, cause sometimes that's worse than matching traffic that's speeding a bit.
Others have made better points but I want to add another thing to point out you can also be making the same "is-ought" mistake yourself:

Impaired drivers (drink, drugs, sleep), bad drivers, dangerous drivers, etc. who ought to use the self-driving function are exactly the kinds of people who won't and continue to drive badly.

What this means is the safer drivers leave it off (because they outperform the system), while dangerous drivers also leave it off because they mistakenly believe they outperform the system. The traits that it's meant to protect people from are the very traits that ensure it can't do its job.

When it is good enough, we should remove the ability for humans to drive cars manually in all new cars after that point.
Or even migrate the testing schema to more frequent re-checks and a harder pass condition.

If people don't have to drive to thrive in society, we can make driving far more of a privilege. Contrast what a private pilot has to do to get certified.

Unfortunately, we can't replicate your mother and put her behind the wheel of every vehicle in America. But we can crank out thousands of autonomous vehicles with thousands of identical copies of highly tuned safety algorithms.
If you had a new born to take home from the hospital and were 20 miles from home.. would you take an autonomous car or have you or a family member drive you home?
With emotions running high surrounding this newborn, me, or a family member, is likely to be stressed, under-slept, possibly drinking. Why wouldn't I want this hypothetical autonomous car to take us all home safely?
Because the math shows that currently it drives about as bad as a sometimes high, drunk, sleepy, angry person. If you had a family member that cared about you available to drive, they would be much safer than the typical ai car right now.
> Because the math shows that currently it drives about as bad as a sometimes high, drunk, sleepy, angry person.

This is surprising. Got a cite for that?

The closest I've come to killing another human was when I was driving to the hospital at night to pick up my wife & newborn, sleep-deprived and high on adrenaline, and came this >< close to taking out a cyclist I completely failed to see.
But one of the points of self-driving cars is to remove those bad drivers from the driving seat.
Maybe in theory, but then you have a bigger social/psychological/economic problem because these populations are necessarily the ones that are going to be compatible with the business model for autonomous cars.

And if you get a bigger proportion of “good drivers” in autonomous cars than there is in the overall population, you're on fact increasing the overall number of accidents.

I agree that a very probable outcome is that the real bad drivers will, for one reason or another, keep using non-self-driving cars way longer than good drivers. But also a good self-driving car should have faster reflexes than a good human driver, so it might mitigate anyway the damage done by a drunken driver.
How? There will be multiple decades of self-driving — human driver co-existence. I’m not convinced that this phase would be safer than the human-only one, as AI might very well handle bad human drivers much worse (as it is an edge case).
I have never once heard self-driving cars sold with the argument "they're great for sleep deprived and alcoholics".

Maybe they should be.

I have always wanted a self-driving car so there's no more "designated driver" hassle with going out.
Same, there are few places I go to I may not come back drunk!

This, and freeing up the streets from parked cars. If cars are self driving they can go park themselves into some big, far away car parks instead of clogging the streets. In europe it can easily multiply by 2 or 3 the throughput of most big cities.

"Going out" is synonymous with drinking? You could just... not drink.
There's a cultural dimension.

In general south europe culture it is normal to drink wine to food, and enjoy it, but also embarrassing to get publically drunk.

Whereas in northern europe, though, it's all beer or spirits and the aim is to get as drunk as possible as quickly as possible.

These generalisations are based on my own observations. There's doubtless a lot of variation.

You're in the write direction but I think you don't have the right words to describe what you're trying to describe. I made a sister comment, but if I correctly understand you, then it would be more accurate to say that the averaged statistic removes important variables for making accurate conclusions. We need not look at your mother, but we can consider different environments. I think most of us would say it would be silly to compare accidents on the highway to accidents to those in an urban street, but an "average by mile" is doing precisely this. We'd call this "marginalization" and it is why you should be suspicious when anyone discusses averages (or medians!). (On that note, the median and average are always within one standard deviation of another. It's useful because if you have both and they are far apart you know there's a lot of variance). I hope I accurately understood you and can help make a clearer message.
> why you should be suspicious when anyone discusses averages

I like to say that the average human being has one testicle and half a vagina, which is not very representative of anyone around.

> On that note, the median and average are always within one standard deviation of another

Oh really? That's cool.

Haha yeah that is accurate. The right language is situational though haha. People are generally overconfident in their ability to mathematically describe things. There's a clique "all models are wrong" and like all cliques it is something everyone can repeat but not internalize lol
you should not forget the second part: all models are wrong, some are useful
Yes, but unfortunately the second part is usually employed by people who want to put under the rug the fact that their model is dubious.

All models are wrong, only some of them are useful, and only when handled with care.

The second part is the obvious part that often doesn't need restating. Models can be incredibly powerful tools.
> It's useful because if you have both and they are far apart you know there's a lot of variance

ummm. I would refrain from using nonparametric skew to make a comment about the magnitude of variance.

Essentially, the gap between mean and median will always be bounded by 1 sigma. The ratio abs(mean-median)/sigma is nonparametric skew. It is atmost 1, for any distribution( hence nonparametric, no distributional assumption required).

For unimodal distributions, especially symmetric unimodals, this ratio is 0. As the gap between the mean and median grows, the data gets more spread out, and the ratio captures that spread and consequent nonsymmetry. But you are using the value of this upper bound to make a comment about s^2. Which is very clever, but inaccurate. Say you standardize the rv and you have a nonsymmetric dist. Then mean 0, say median 100. Then stdev can be atmost 100, so variance can be atmost 10000. Which looks like “a lot of variance”. But is it really? Variance has a scaling problem, precisely why we take the square root, so the stdev remains in the scale of the mean. So at best one can say the stdev can be as big as the median. But that’s not very informative- because if the mean is -50 and median is +50, we are left with the same absolute gap of 100, so the same statement applies to the stdev even now.

I guess if I had to compare the variance of some sample X to another sample Y to make some claim that variance of X is much larger than Y, I would use a standard F test. Cooking up a test based on the gap between mean and median in a single sample seems somewhat shaky. It is very creative though, I grant you that.

Perhaps I gave the statement too much strength, far more than intended. But I don't view any metric as anything more than a guide. The reason I use parametric skew in this way is explicitly for a quick and dirty interpretation of the data. Essentially trying to understand if I should take someone's data at face value or not. It's about being a flag. The reason is because when going about the world in an every day fashion I am generally not going to have access to other data like variance (which if we did, we wouldn't need this hack) and can't really do an F-test on the fly. Usually you're presented with the mean and it can still be hard to find a median but it is usually more obtainable than the variance or any other information. So I get your concern and I think you are right for bringing it up because how I stated things could clearly be mistaken (I'll admit to that) but wanted to assure you that no strong decisions were being made using this. I only use it as a sniff test. I do think it helps to give people a bunch of different sniff tests because it is hard for us to navigate data and if you're this well versed I'm sure you have a similar frustration in how difficult it can be to make informed decisions. So what tools do we have to can set off red flags and help us not be deceived by those who wish to just throw numbers at us and say that this is the answer?
But your mother is still better off with the drunks not driving (they may crash into her car). So she may still have less accidents in a world where everyone goes self driving.

This will still leave us with the random and dangerous behaviours of cyclists and motorcycles though.

The problem will all of these stats (although some like Waymo are better than others like Tesla), is that the bare number is quite misleading because they compare apples to oranges. Firstly Waymo (and others don't often don't operate in places that they have excluded or they don't know. Humans drive in unfamiliar places (which I'd bet changes the chances of accidents). Moreover, waymo might decide to not operate in some places at all because they deem the traffic/road conditions to dangerous (and I think that's a good thing), however human accidents in those areas (which are by the condition are more accident prone) still go into those statistics.

It's similar for weather, self driving cars might refuse to operate in some weather conditions (I don't think it's by accident that most companies mainly operate in the relatively warm and sunny places of the US), human accidents under bad conditions are still part of the statistics.

And again drunk/impaired drivers also go into the statistics, if we disregard them and humans become safer, than this is not an argument that self driving is safer than humans, but an argument that there isn't enough enforcement around riving impaired.

> We can compare this statistically by looking at accidents per 1,000,000 miles driven of autonomous cars vs humans.

This is extremely limited and really not relevant to the topic at hand. You've marginalized out the type of accidents. Most miles driven are on highways and this is a different environment than urban. The information you've marginalized out is essential for making reasonable conclusions about safety. It isn't important to just know the ratio of TP/TN/FP/FN but more specifically where and when these errors happen. The nuance is critical to this type of discussion and a simplification can actually cause you to make poor decisions that are in the wrong direction rather than naive decisions but in the correct direction.

I can guarantee you there are more accidents per 1,000,000 miles driven in dense urban areas, and that's where Waymo has been driving as well. Last I checked they're not even operating on freeways.
I highly recommend reading through Waymo's own publications that addresses these exact concerns: https://waymo.com/safety/

Specifically "Framework for a conflict typology including causal factors for use in ADS safety evaluation" and "Comparison of Waymo Rider-Only Crash Data to Human Benchmarks at 7.1 Million Miles"

It may not surprise you to know that they have given a LOT of consideration to these factors and have built a complex model that addresses these to demonstrate their claims.

That's terrible statistics. Let children drive and the self-driving cars would be, on average, even more safe!

Comparisons should be made 1) with the median, not the average, and 2) under the same conditions.

If we are going to use flawed statistics of autonomous cars vs humans, we should first look at even better examples then waymo. Im pretty sure Mercedes Level 3 driving automation for the Autobahn is safer, as well as autonomous cars that park cars at airports. Their accidents per 1,000,000 miles should be 0, a statistic which is hard for humans to beat.

The more restricted and environment controlled we can make it, the few accidents we see machine controlled cars do, and the worse a adaptive human driver does in comparison (barring extreme situations).

On the other hand there are many human drivers who will endanger cyclists on purpose because they either don't like them or are inconsiderable aaaholes in general and engage in dangerous behaviours like speeding, overtaking when there is incoming traffic from that other direction (cause they think it's safe to squeeze in as cyclists are small) or not paying attention to right of way signs.

Speeding alone is a huge problem. I would take self driving cars even if far from perfect just because of it. It will be safer if they don't speed even if they sometimes randomly drive into other vehicles. Everything is secondary when it comes to safety. It really is obvious when you move from a place where people don't respect speed limits to one where they do. I think not speeding solves 95%+ of serious safety problems.

The converse argument is that human drivers hit cyclists everyday, and we never hear about them because they are not unusual.
Yet it makes me wonder how the car would react if it came to a stop on top of the leg of the cyclist or in some situation where a normal driver would notice that he should get into the car again and back up a couple of feet.

I'm not against Waymo.

My mom was hit by a driver when she was biking and fell with her arm in front of the wheel. The driver then decided to pull forward and drove over her arm. So humans don’t really solve that problem.
Getting big "this is actually good for Bitcoin!" vibes from this. I don't think we can fairly assess who was at fault, given that none of us were there. But it is insane to just assume a manned vehicle would have fared worse, and declare it a victory for driverless cars.

I don't hate cyclists, I've used a bike as a primary form of transport for much of my life.

But especially in the US, dangerous behavior from cyclists seems to be proportionally much more common than dangerous behavior by Waymos. So yeah, it's easy to believe that a cyclist just kind of blew the stop sign when they shouldn't have.

> behavior from cyclists seems to be proportionally much more common than dangerous behavior by Waymos

I'm not trying to take any position to this notion. I don't know the facts. I only know that not coming to a complete stop (different from blowing throw an intersection!) does not equate to dangerous behavior. You'll find another link that shows evidence otherwise. "Stop-as-yield" laws would be worth looking into if you're interested.

I'm well aware of the Idaho stop, I'd advocated for it on many occasions.

However, I'm also aware that a lot of cyclists don't 'yield' so much as 'continue at full speed through the 4-way stop sign'.

So far, Waymo seems to have a culture of playing things very by the book and safely, or at least as safe as possible given the constraints of developing self-driving cars on public roads. I think it's very unlikely they'd lie, knowing that they'll have to hand over footage of the incident over to the authorities, and especially given what recently happened with Cruise semi-lying and being absolutely thrashed in the press because of it.

> You must not live in SF if this is unexpected for you.

OP didn't say surprised, they said disappointed. For example: I am not surprised that I burn my food because I left it in the oven too long, but I am disappointed that my food is ruined. Be careful not to conflate the two and impose beliefs on another person that they may or may not have. If you're talking politicians, I would say that such notions (pinning fictitious ideals to a person or group) are common tactics and this seems explicitly what you are upset about (as I think many are). So let's not engage in similar behavior, it only enables those tactics.

Nothing should surprise you about Shamann Walton. This is the man who refused to adhere to the City Hall's security procedures (on camera) and allegedly threatened the person who asked him to comply: https://sfstandard.com/2022/08/05/video-supervisor-shamann-w...

He also bought a home outside San Francisco, with a mortgage condition that says it must be his principal residence. But if doesn't live in SF, how can he represent the people of SF?

I'm not surprised by the content of your links, but I can say I'm disappointed. After all, surprise and disappointment are different things.
> After all, surprise and disappointment are different things.

Hmmm... I think I gave it a honest try, but I'm still having trouble making that fit. I mean, both are when the unexpected occurs, one is just more-specific, where the unexpected leads to a negative emotional response.

Perhaps shocked versus disappointed?

In a similar comment I gave an example and maybe that'll help. I can leave my food in the oven too long and I will not be surprised to find that it is burnt, but I will definitely be disappointment that I ruined my meal. I think this should clarify and why I was a bit snarky lol. While they often correlate they are not the same.
> I can leave my food in the oven too long and I will not be surprised to find that it is burnt, but I will definitely be disappointment that I ruined my meal.

Wading deep into the philosophical weeds here, my instinct is saying that's not an apples-to-apples scenario, because each term is being used in connection to different sets of events. For example, "when I realized my alarm hadn't gone off" versus "when I got home and opened the oven door."

Perhaps the easiest way to illustrate that is to imagine the opposite scenario, where all discoveries and all self-analysis occur at the same moment in time:

1. You ask someone else to bake a pie, let it cool, and deliver the result to you later in the day.

2. A few hours later, an opaque and airtight box arrives, on time. (No clues, no warnings.) You still anticipate it contains your favorite pie.

3. You open the box to discover a blackened stinky mess!

4. At this moment you are experience both surprise (in general) and also a specific sub-type of surprise which is disappointed surprise.

Based on waymos description, it seems pretty cut and dry that this was literally an “accident” where the biker maybe should have waited until the lane cleared and any car would have hit them in the same situation. If anything they can use this data to see how it maybe could be prevented in the future.

Maybe waymo was still in the wrong for some reason? Sadly the article that goes in depth after we have more details and can more clearly report if waymo is to blame will likely not get nearly as much traction as this headline.

I'd like to see a video. If a car is turning, it would presumably be travelling slowly, and wouldn't be trying to cut right behind a passing truck when there's no visibility.
I believe based on the description that no one was turning. The truck and the waymo vehicle were traveling parallel to one another, and the cyclist was at 90 degrees. If this is correct the “behind the truck” would mean occluded by the truck rather than following the rear of the truck. If that is true the cyclist and the waymo vehicle couldn’t see one another due to the truck, and both began entering the intersection. My guess is the cyclist was also unable to come to a stop when they saw the waymo vehicle. I think we would need to know a lot more to assign fault though.
Maybe the accident could have been avoided completely if the Waymo car drove more defensively? The article doesn't mention how fast it was travelling before it applied the brakes, but maybe it would be better to drive extra slowly while it can't "see" to the left because of a truck when driving through an intersection? Or not proceed into the intersection at all before it has a clear field of view?

Of course there is also a balance between safety and practicality here. Above a certain level of traffic congestion, I assume even Waymo cars have to be a bit "assertive", otherwise they would wait for hours at a stop sign...

I’m happy that in the Netherlands it’s ALWAYS the car driver’s responsibility (she always pays).
I don't agree with most laws that impose absolutes. The courts exist to deal with grey areas.

A large number of pedestrians struck by cars each year (at least in North America), are themselves intoxicated, and not fit to walk along roadways. There are many cases where the driver should not reasonably be at fault for a pedestrians erratic behavior.

There's also the "hit-to-kill" phenomenon in China, where it can be financially devastating to leave a person living with significant injuries, but affordable if you had simply killed them (50K USD vs 1M over a lifetime). In extremely sad circumstances, this has motivated people to hit the victim multiple times.

You mean laws that forbid pedestrians from crossing roads? It’s just a matter of where you put your priorities. Here we prioritize our bike based transportation. Drivers just have to be careful, also insurance is obligatory so drivers don’t really feel it financially. They just pay collectively for all the other traffic participants they hit.

We have a very different system, nobody goes bankrupt from causing an accident or from healthcare related costs.

I am a cyclist myself, and let me tell you... cyclists are the fucking worst. Many of them drive so recklessly, like going full-speed through an intersection while their traffic light is red. There is just no way in many cases for a car driver to avoid hitting such idiots, no matter how much attention they pay. Neither cars nor bicycles can just stop on a whim, they need a couple meters to do so.
That is a US perspective. We don't have "cyclists" everybody uses a bike from time to time, our infrastructure is build for it [0], and when you get your driver’s license your learn how to deal with it.

[0] https://www.youtube.com/watch?v=ynwMN3Z9Og8

I hate the thought of being restricted to that slow speed. But my look at the throughput!
I call bullshit on "unfit to walk along roadways". This is victim blaming from people who want to go fast, fast, fast.

The one moving a ton of metal is the one to pay attention. And the US needs to build roadways actually usable by pedestrians.

Pay some fucking attention in traffic, even if you are on two feet instead of on wheels, for fuck's sake!
Would you say this to bereaved parents?
A lot of pedestrians are kids, who by their nature are erratic. Saying that it's the kid's fault for getting hit because they were "erratic" is effectively banning children from walking places, which is exactly what the US has done ("WHy don't kids play outside anymore???")

The person operating the dangerous machinery where there could be people walking bears responsibility for not hitting people.

This is all true. As a driver, you are definitely expected to be aware at all times. Things like schoolzones enforce drivers being more aware and slowing even more. We have rules to not pass school buses when children are departing. We have speed limits that are lower in suburbs.

Even if you follow all of these rules, theres not too much you can do about someone suddenly staggering infront of your car. Obviously if you see them ahead of time, be even more cautious.

(also drunk people are in-part banned from roadways- public intoxication is a misdemeanor)

Sometimes it’s unavoidable, and then your insurance will take care of it as will the care system. You are responsible but you won’t pay, your obligatory insurance will.
If there are intoxicated people around, or children, it's necessary to reduce driving speed.

That can mean moving at walking pace, or remaining stopped entirely, if you happen to be driving past a concert hall as everyone is leaving, for example.

>A large number of pedestrians struck by cars each year (at least in North America), are themselves intoxicated, and not fit to walk along roadways. There are many cases where the driver should not reasonably be at fault for a pedestrians erratic behavior.

Excuse me? How can someone be unfit to just walk somewhere just because they're drunk? You don't need a license to walk!

You don't need a license to go downhill skiing, but you still shouldn't do it while intoxicated.

But yes, if it is unsafe to walk home while drunk, that's an infrastructure and safety problem more than it is a failing of the drunk person.

No, that is absolute bullshit. So so often, it is obviously the reckless cyclist's fault.
That's a US perspective you have a car-first culture. If you have a bike first infrastructure you wouldn't talk like that. Here Bikes and cars are often even on different roads, where they need to cross, it's made very clear how that will work (traffic lights, clear lanes).
I mostly go on foot and… I'd go for a bicycle is always at fault law to be honest. Meek with cars and assholes with pedestrians is how cyclists mostly are.
You obviously are not from a culture where everybody is a cyclist. We have more bikes than cars in our country because you can use them at all ages and get to more places using a bike. My kids learned to ride a bike at 2.

We have some research [0], on average anybody over 6 rode a bike 232 times and an average of about 1000 km in 2022.

I'm from a culture where mountains exist. Geography isn't a culture.

Having said that. In Sweden this routinely happens:

To clear the bike and car paths from snow, a mountain is of snow is made over the pedestrian path, then INEVITABLY bicyclists angry ring at pedestrians all the time… because pedestrians should walk in 1 meter high piled up snow of course?

The same also happens if there is a digging in progress and there is a 2 meter hole… cyclists still expect pedestrians to jump down in a hole and then climb up.

However where there is no bicycle path, they will go on the side walk (which is not allowed).

Of course a good % of them actually have an electric engine and zoom around very fast.

You are an angry person. Most people are kind, something is not adding up here.
I am not angry until some person on the bicycle tells me to go to hellvete (hell, but it's more insulting in swedish than english) because I dared to walk on the cleared up bicycle path when there was no alternative.

After, I do tend get angry, yes.

You are probably just set in your own ways and refuse to internalize that there's more to the experience of the human race than your little bubble.

He man we all know Klingons have anger management issues.
Victim blaming at its best.

Perhaps it's time to do some serious self evaluation.

No, that is the perspective of a sane person. God damn it. I am European, and I - without a driver's license, so just a cyclist and pedestrian btw - have to deal with the behaviour of the entitled cycling shits every day, especially since I moved to Berlin. Occasionally also with pedestrians that just suddenly step onto the street without even looking. Surprisingly, the car drivers - even though they are assholes in Berlin, too - have been by far the most sane traffic participants to me so far.

I have seen quite a few situations with cyclists behaving so ridiculously recklessly that the only reason I can see is that they must have a death wish. But yeah, sure, blame the car for running into a cyclist who runs a red light over an intersection at full speed, suddenly appearing between two lanes of standing cars. Or for running into a cyclist driving on the left side of the road into an intersection without looking. Or blame me for running into a pedestrian who suddenly steps in front of me. Ah no, wait - you're a hardcore cycling apologete, I am sure the pedestrian would be at fault in this particular case, right?

You have a perspective I don't recognize.

How often are you gonna copy-paste your arrogant nonsense?
It isn’t ALWAYS.

https://en.wikipedia.org/wiki/Strict_liability#Bicycle–motor...

“In a nutshell, this means that, in a collision between a car and a cyclist, the driver is deemed to be liable to pay damages and his insurer (n.b. motor vehicle insurance is mandatory in the Netherlands, while cyclist insurance is not) must pay the full damages, as long as 1) the collision was unintentional (i.e. neither party, motorist or cyclist, intentionally crashed into the other), and 2) the cyclist was not in error in some way. Even if a cyclist made an error, as long as the collision was still unintentional, the motorist's insurance must still pay half of the damages. This does not apply if the cyclist is under 14 years of age, in which case the motorist must pay full damages for unintentional collisions with minors. If it can be proved that a cyclist intended to collide with the car, then the cyclist must pay the damages (or their parents in the case of a minor.).”

Maybe "so much for safety" refers to the cyclist turning left without looking.
I appreciate your optimism.
I'm disappointed with all the folks like you who blame no one but an SF employee
As somebody who uses a bike as primary mode of transport for myself and my entire family, it's pretty normal for American officials to immediately blame people on bikes for getting killed. I would be thrilled to see them be as concerned about humans killing people with cars as about computers doing it.

Honestly I'd feel much safer if all cars were not driven by humans.

I was struck by that supervisor comment too. I don’t live there anymore but when I did that was always the looming issue.
(comment deleted)
Can’t wait for all the comments telling me its ok because people also hit bikers.
Agree that's not a great look for the supervisor.

Cyclists have a bad rep in SF because many (not all) ride quite dangerously. It's a common sight to see cyclists running four-way stop signs and lights without even yielding. I live adjacent to a four-way stop and there's an incident where a cyclist fails to yield nearly hourly.

Meanwhile, Waymo has millions of incident-free miles and of all the self-driving car companies generally takes safety seriously, even if they will act to protect their interests here.

Until more evidence comes out I'll be taking Waymo's side here. I want safer vehicles and Waymo is currently the best bet.

> Cyclists have a bad rep in SF because many (not all) ride quite dangerously.

Cycling in the US is almost by definition riding dangerously, since there are very few places with actual safe bicycle infrastructure. This is a self-selecting pressure, because it means that the only cyclists that actually dare to cycle in the city are risk-takers.

> I live adjacent to a four-way stop and there's an incident where a cyclist fails to yield nearly hourly.

You can blame the cyclist or perhaps a four-way stop with a nearly hourly cyclist incident needs to be redesigned.

"> I live adjacent to a four-way stop and there's an incident where a cyclist fails to yield nearly hourly.

You can blame the cyclist or perhaps a four-way stop with a nearly hourly cyclist incident needs to be redesigned."

Or, bear with me here, just maybe the cyclists failing to yield is kind of the big issue here?

No it’s not. AB122 passed the legislature to legalize the California roll for cyclists, because coming to a full stop at a stop sign makes no sense for riders with high visibility. Newsom vetoed it for stupid culture war reasons. It’s a law that doesn’t make sense so it’s not a big issue if it isn’t followed.
I'm a cyclist and support these types of laws. But I could imagine someone making the same case for a car (or a motorcycle?). You can have high visibility and come towards a 4-way stop in the middle of nowhere and there's not another car in sight. It doesn't really make sense. For cycling of course it's super annoying to lose your momentum.
Considering:

> annoying

Vs

excess CO2 from engines (does not matter if electric or not, as efficiency is still a thing to consider) after a full stop,

would it make more sense to make cyclists to yield always and not cars?

I see cars in the city roll through stop signs all the time, but I never heard of a bicyclist killing someone while blasting through a stop sign. The difference between bicycles and cars is based on the potential for harm.
> because coming to a full stop at a stop sign makes no sense for riders with high visibility.

For anyone wondering why I give an explanation here[0]. The tldr is you need to move to be safe and it is harder to get a bike moving than it is a car. It's best to contextualize any such arguments around the operations that go into operating the vehicle and cars and bikes have a lot of differences. Those differences are why cars are more popular (Sure, more energy but motor vs legs. If you want to make the argument that it is easier for a bike you better not get frustrated when a bike is slow to get to speed when you're behind them at a stoplight or stop-sign).

The comment you link to has been flagged.
Thanks for the notice, I'm not too concerned though. I didn't violate any rules. People must be upset that I made an argument that it can be safer to not come to a full and complete stop. But I'm not making the argument that it is safe to blindly blow throw an intersection either. Given the comments I'm seeing, it appears that it is difficult to differentiate these two things.
Failure to yield is a separate question from should they be required to stop if nobody is present.
California roll != failure to yield. I swear some in here would argue water isn’t wet and the sky isn’t blue…
It's simple selfishness. Cyclists don't want to lose their momentum. Coasting is fun and exertion is not; humans evolved to minimize their energy expenditure. To fix that, you'd need to redesign the bicycle to be completely battery powered. Even then, acceleration will be slower than not stopping. Cyclists will try to rationalize their behavior in all kinds of ways, but they're just lying to themselves (and you).
> It's simple selfishness.

This is a weird characterization of what's going on given you have an apt description. I've only been struck by cars (twice) when stopped at a stop sign. It's no question that an intersection is one of the most dangerous locations for a cyclist and it is also no question that an intersection can be cleared significantly faster when starting with __any__ amount of momentum vs a complete stop. Specifics will be necessary for making adequate conclusions here. Someone blindly blowing through an intersection certainly clears the intersection faster but that alone doesn't mean the behavior is appropriate or any less idiotic. And someone doing that is very different from someone slowing down and treating the stop sign like a yield sign. An over generalization is just going to lead to irrational conclusions because context is necessary.

Don't give them the time of day. I never understood why cyclists acted the way they act until I started commuting to work. I felt unsafe at intersections when stopped. I felt unsafe at intersections when starting slowly. I read online about some road rules making my trips more dangerous for ME, not the cars. Now I know what I can do that's totally illegal that's keeping me safer.
Cycling is dangerous when mixed with cars, for sure. But blazing through at an intersection full of cars which are expecting you to stop is even more dangerous. Stop sign rules exist for a reason (to slow vehicles down enough that everyone can see and negotiate everyone else) and it's safer for all if you obey them. This is an example of the rationalization I alluded to earlier. Cyclists lie to themselves.

Next you will be telling me that changing lanes without signaling or looking, swerving through traffic, ignoring stop signs on bike paths, riding while looking at one's phone, riding the wrong way, riding without a helmet, or at night without lights (all of which I observe all the time from cyclists) are evolved safety behaviors.

This is not to excuse drivers, who do lazy and selfish things all the time, like looking at their phones. The root cause is the same--human nature. It just so happens that the incentives are worse when cycling.

> Next you will be telling me that changing lanes without signaling or looking, swerving through traffic, ignoring stop signs on bike paths, riding while looking at one's phone, riding the wrong way, riding without a helmet, or at night without lights (all of which I observe all the time from cyclists) are evolved safety behaviors.

You've just described the average cyclist in Amsterdam. They'll do all of that at the same time with a passenger sitting on the rear baggage carrier.

Yet the Netherlands has one of the lowest mortality rates per mile cycled and the US has one of the highest. Despite the US having very strict full stop laws for cyclists.

28% of vehicle fatalities in Amsterdam are cycling related. Deaths do happen. If you’re arguing that these behaviors are, in fact, safe, I would disagree strongly. The U.S. drives large trucks at high speeds because the U.S. isn't very dense, even in cities, and car centric. And bike infrastructure is lacking. I agree, making cycling safer makes cyclists safer. But none of this explains why cyclists bike like a*holes in every country, which is the point I was making. In addition to the physics of bikes encouraging selfish behavior, there is the lack of license plates and ticketing.
> 28% of vehicle fatalities in Amsterdam are cycling related. Deaths do happen.

Of course, none of those behaviors are safe. And mandating lights, a helmet, high visibility jacket, kneepad protectors and a license plate would make a cyclist safer. (And lights are mandatory even in Amsterdam)

But it would also discourage people from cycling by making that mode of transportation even more inconvenient than it already is compared to the car. And so because, as you noted, humans seek convenience; they will take the car instead.

> But none of this explains why cyclists bike like a*holes in every country, which is the point I was making.

Again it's self-selecting, since there is no bike infrastructure and you ride in between large trucks you have to be very assertive in traffic. Which tends to select for the more stand-offish types.

Not like the altruistic endeavor that is driving a car in a dense urban environment. Those are the real heroes.
The fix is really quite simple, develop separate routes for cyclists and motor vehicles. Where those routes unavoidably cross have proper intersections. The person you are replying to is right, four-way-stops are a travesty, both for cyclists and cars.
Sure, have fewer stops. But even if you separate the routes, cyclists will eventually have to stop somewhere (even for other cyclists), and they won’t want to.
You'll see a lot more cyclists acting safely if it's actually safe to cycle. Dangerous cycling infrastructure scares away safe cyclists, so all you're left with are the daredevils who won't stop for anything.
It's actually more tha bikes don't have license plates, and aren't pulled over and ticketed by cops. The anonymity drives lawlessness.
Incorporating manual vehicle operation into the driving test could significantly alter driving habits, a change I've personally experienced after learning to drive a manual as an adult. As GP notes, the desire to conserve energy and avoid stopping and then starting again is common among cyclists, and this principle applies to manual vehicles as well. Having been raised in the U.S., I understand the potential chaos of having no stop signs or traffic lights at busy four-way intersections. However, this system functions effectively in major cities globally, where drivers, perhaps more accustomed to manual vehicles, approach and navigate intersections with greater awareness and negotiation skills.

I believe that mandating manual driving lessons for all learners could foster improved driving behaviors and heightened road awareness. This approach could encourage drivers to be more attentive and considerate of other road users, enhancing overall safety and efficiency on the roads.

> I live adjacent to a four-way stop and there's an incident where a cyclist fails to yield nearly hourly.

When I see systematic things like this I often get suspicious and think there is something more going on (or selection bias. We are human). I think the common model is attributing actions to reckless behavior and people not thinking. This very well may be true! But if people are consistently engaging in a specific behavior (reckless or not) there's usually a reason to it. Reason doesn't mean good reason btw, and it can be as dumb as the previous chimps getting hosed every time they try to get the banana, but that's still a reason. I think if the underlying reason can be found it significantly increases the chances of rectifying the situation.

> Until more evidence comes out I'll be taking Waymo's side here.

Until more evidence I'm holding out on taking a side. I think Waymo's safety record is orthogonal to the conversation as with the general safety record of driverless cars (which I am a big fan of fwiw).

Because stopping with 4000-lb cars lined up behind you is safer?
Even with a cyclist disregarding the law, it shouldn't be possible for a law abiding autonomous vehicle to collide with anything if it had confirmed the intersection was clear of traffic. Seems like it assumes an unoccupied slot behind trucks that won't always be true. What if this was a T-intersection where a cyclist wasn't obligated to stop?
Ah, but people yelled because waymo was too timid. They probably did that because it's how people are expected to drive in California. Bit of a sticky wicket for waymo isn't it?

I tried this line of reasoning with a judge once. If you break the law just because people expect you to, it's still your traffic violation.

>I live adjacent to a four-way stop and there's an incident where a cyclist fails to yield nearly hourly.

You should try paying attention to the cars. I live near one (elsewhere) as well and I see cars driving straight through it all the time. Why have a double standard?

I think all of us agree that cars shouldn’t blow through intersections, neither should bicycles. It definitely raises my eyebrows more if cars do it (rare but sadly increasingly less rare) vs if bicycles do get it (fairly common).
> It definitely raises my eyebrows more if cars do it (rare but sadly increasingly less rare)

It is extremely common, the default really, for cars to roll through 4-way stops.

A rolling stop is not blowing through which he was talking about I think.
When cars do a “rolling stop” what they are really doing is slowing down to 10-15mph, which is the same speed as a cyclist “blowing” through a stop sign at full speed.
I live in Seattle, so you’ll see bikes mostly blow through stop signs going down a decline, they can faster than 10-15 even without e-assist. Cars, when they do ignore the stop sign, can be going up or down, however. If I see a bike going downhill approaching a stop sign, I assume they are going to try and ignore it if it won’t obviously get them killed. Uphill, bikes care more about stopping since they aren’t losing momentum.
Maybe where you live? It isn’t as common here in Seattle, although as I said it is definitely becoming less rare.
> Cyclists have a bad rep in SF because many (not all) ride quite dangerously. It's a common sight to see cyclists running four-way stop signs and lights without even yielding.

Pick any stop sign in SF. Watch it for an hour and count the number of cars that come to a complete stop. The denominator doesn't matter because the numerator will be ~0.

> count the number of cars that come to a complete stop

You’re conflating two different phenomena, perhaps purposefully.

California drivers do often fail to come to a technical stop at intersections, but they first slow to a near-zero speed that very nearly accomplishes the same purpose.

In contrast, a large number of cyclists do not slow at all, and blast through red lights at full speed.

The full speed being, of course, about the speed of a car doing a california roll.

Google “cyclist stop sign safety”

> In 1982, Idaho was the first State to pass such a law, commonly known as the “Idaho Stop Law.” The law allows bicyclists to yield at stop signs and proceed when safe, rather than come to a complete stop. After Idaho adopted the law, bicyclist injuries from traffic crashes declined by 14.5% the following year (Meggs, 2010). In 2017, Delaware adopted a similar, limited stop-as-yield law, known as the "Delaware Yield.” Traffic crashes involving bicyclists at stop sign intersections fell by 23% in the 30 months after the law’s passage, compared to the previous 30 months.

You're restating their point but I don't think you get it. "a large number" is a vague term and I think we would be apt to say "a large number of cars run stop signs." The big issue at hand is selection and perceptual biases. If we're just going on intuition here we're going to make bad decisions. You will not notice the "large number of" cyclists that have appropriate behavior because this will be normal behavior that is non-disruptive and your brain is designed to not take special notice of this. But your brain is designed to take special notice of rare and/or disruptive events. So you always over inflate those numbers and it is hard to accurately quantify. See "Perceptual vigilance" for more.
I've lived in San Francisco for over 4 years. I cycle, walk, drive, and take public transport. If I were about to cross at an intersection with a stop sign, the sight of an approaching car would create more fear and caution in me, than would the sight of an approaching bicycle.

> California drivers do often fail to come to a technical stop at intersections, but they first slow to a near-zero speed that very nearly accomplishes the same purpose.

It very nearly accomplishes the same purpose only from the point of view of other drivers. When a driver in SF approaches an intersection, they're looking out for other cars, working out whether they'll be able to slow down and continue, or they'll need to stop. If they don't see another car that will have priority, they won't stop. So:

- they may not see the pedestrian that's just reached the intersection, and/or

- the pedestrian that's just reached the intersection won't know whether the car is going to stop, so they won't attempt to cross

When I drive, I'm sometimes frustrated when I stop at an intersection, wait for a pedestrian to start crossing, and they're slow to get started. Then I remember it's the behavior of drivers that has conditioned pedestrians to yield even when they have right of way.

There's a difference between stop and slow down. There are some people who barely slow down and that's totally illegal and blatantly bad. It's also a minority of the time. Most people do significantly slow if not stop at intersections, regardless if there's another car with the right of way or not.

This is a big mischaracterization. That said, I do see cyclists blowing through stop signs ALL THE TIME, often totally dangerously with other cars (including me) at the intersection with them.

> There's a difference between stop and slow down.

Yes, that's exactly my point!

Going 2mph through a stop sign is materially different from stopping at the line. When you stop, you can confirm that the intersection is clear (and that there are no pedestrians about to cross).

If you had to guess, what would you say is the median speed of cars across the lines at stop signs in SF?

I guess we drive in different parts of the city. I see this, but not often.

I’d say the median speed is 0, since probably a majority of the time there are other cars.

I see bikes blowing through all over the city, not just where I live. Just yesterday I was in the Richmond and a bike not only didn’t stop but it was AFTER I was fully stopped at the stop sign and about to start driving.

I similarly have mixed mode of transportation. I'll admit that when walking I will frequently fully stop in the middle of crossing an intersection. Many people do come to abrupt stops at stop signs and from the perspective of a pedestrian it is difficult to differentiate, especially when it is unclear that a driver sees you. I sure am not going to risk it, so I stop, and am sure to make sure that driver sees me. But similarly, it makes me more sympathetic to pedestrians and cyclists and I will approach intersections differently when they are around and do my best to make sure they know I see them. When driving, walking, and cycling you are operating in very different environments despite being in the same place. People tend to do things for reasons and if an action is common within a group it would be naive to not consider why this behavior develops.

This is a complete waste of time until video or a decision based on video is released.
HackerNews has a major problem with regards to victim blaming as it pertains to cyclists, and this thread is clear evidence of it.
It's a classic flamewar topic with plenty of people on both sides feeling similarly about the other.
The system and society built and maintained for cars is the problem. Not robot or human drivers.
>According to Waymo, the company’s vehicle fully stopped at a four-way intersection before proceeding into the intersection as a large truck was driving through in the opposite direction

and that is a traffic violation on the part of Waymo. From the STOP, you can't go into intersection until it is clear.
