Anecdotally, both from riding in them and walking/driving next to/around them, this feels obvious. They never get distracted. Sure, they sometimes make mistakes, but the mistakes are never "I didn't see that". They see better than humans in all cases (where they operate). They react faster than humans.
The one case where they hit a child, it was because the child jumped in front of the car. And they showed that they hit the child at a lower speed than a human would have because of the reaction time.
I would rather be in an area where only Waymo's are allowed than an area where they are banned.
I'd love to cycle more outdoors, but I'm always wary of the risks. How cool would it be if you could hire a waymo as a "team car" and have it follow you around? It could also carry extra equipment...and act as a ride home in case of emergencies.
Someone once said that this is because Waymos are novelty, and they still behave a bit weird, like being slow and undecisive. Which leads to humans being super-careful around them. So the Waymo safety record is actually not their own achievement.
I guess we'll have to wait to one of the two things to happen to really assess Waymo's performance:
1. They need to lose their markings and easily distinguishable features (like a big lidar on top), so they don't get any special treatment from other drivers.
2. They need to be majority of vehicles on the road.
I've been observing their behavior in Atlanta for about the past year. Our roads here are fairly curvy, hilly, and lacking of expected markings, yet I haven't seen a driverless Waymo vehicle make a single odd move. One thing that brought a smile to my face was when I came to a 4-way stop at the same time as a Waymo vehicle at night & I flash my brights to tell the other vehicle to go ahead (southern hospitality) and I see the Waymo immediately begin its course through the intersection. I was so jolted that I began to tail it in order to pull up next to it to see if there was a human behind the wheel. Watching it drive down this slowly descending hilly road with intermittent speed humps and cars parked alongside the main right lane gave me a close up view of its slightly curving trajectory and braking behavior with regard to the humps. My thought on human or not was inconclusive until we reached a red light, and as I shot my eyes over and saw an empty driver seat, I smiled widely knowing that the software responds to brights flashed at 4-way stops (please don't tell me it doesn't and it just saw me indecisively not initiate at the stop). Thanks for reading
“Safer” == “Safer than all other human drivers in the same city.” By their own admission, this is not a straightforward comparison. If they could do the math for the same routes, times of day, and conditions … maybe I’d believe it. Otherwise, this data is trivial to cherrypick, and they have every reason to present it as well as possible.
I believe Waymos are pretty safe, and that’s a great thing. “Safer than humans (for selected rides inside this area)” is still very good, but it’s not at all “Safer than humans (period).”
I live in LA and Waymos are the only cars I don't have to play chicken with when crossing the street. Even the drivers that see you will just give you a "sorry, I'm in a rush" wave as they nearly run you over.
"For example, the current cities Waymo operates in do not have appreciable snow fall, and as a result neither the Waymo nor the human benchmark data include this type of inclement weather."
I'm happy to see this acknowledged, and hope it's a sign that they appreciate the difficulties of winter driving.
They’re in Denver now (not available to the public yet) for this exact reason. Unfortunately we’ve had our least snowy winter in recorded history this year - so they only got a few days of real snow.
My question is: is safer than average human good enough?
When I drive I have the option to choose to be safe or not. When a computer drives I lose that option. So for 49% of the people, safer than the average human is less safe than before.
I think we need to reach "Safer than the safest 10% of humans".
Also these reports should be done by a government agency.
You seem to be thinking this is compared to median driver, and not average one: if most accidents are caused by small number of bad drivers, your average will be bad, but even median might still be good.
And this does not even compare the drivers, but simply miles driven.
So I think that 80% of human drivers would likely be safer than Waymo unless they are driving under the influence or extremely tired or distracted.
Note that "13x safer" already implies being in the top 10%, though.
From a purely technical perspective, I would expect a Waymo to react to unexpected external stimuli much, much faster than a human. It gives the Waymo options that are unavailable to a human's slower reaction time.
Even the most visible academic skeptic of Waymo (Phil Koopman) had to throw in the towel and admit that they've cleared every conceivable statistical hurdle to conclusively demonstrating that they are better than humans on injuries and airbag deployments. They have moved the goalposts to aesthetic arguments, for example: if it's so safe why does it sometimes do weird stuff? But to principled systems thinkers they have already shown what needed to be shown. It's safer.
The great deal: let's redesign our cities to be car free. Consider the economic boom that amount of renovation would produce. Consider the increased economic activity from happier and more productive people. Consider the increased space for nature, parks, real estate, development.
Cars are the worst thing to have been invented. Optimizing the personal automobile leads to optimizing for a horrible living experience in the city. Let us reconsider all of this. This is bad. We can do better. We must.
Anecdote from 1000s of miles biking: I bike a lot in the Bay, for fun, exercise, commute, all of the above (I'm a friendly one, I promise!) and the comfort I feel when I see a Waymo alongside me or at a stop sign is immediately apparent. I have been hit 5-10x riding in NYC and SF (nothing serious, gratefully, mostly just people turning right not knowing/caring I was there), and the Waymo's awareness that I exist is immediately obvious and so different from a large percentage of human drivers. I hope the meaningful improvement in safety continues to convince people this should be a part of the future.
Blaming the kid here is absurd. The kid lives in a system where pedestrians are second class citizens in a world dictated by the auto-petro industrial complex. An industry that has co-opted unelected traffic "engineer" in the US and completely changed the way we live for the last 70 years and have made Americans fatter and less connected.
If the child lived in a neighborhood where cars went slower (it was a 25mph zone) he wouldn't have gotten hit in the first place. Praising Waymo here is like praising a priest for not molesting a child. Yes it's good that the waymo slowed down more than the average car, but really the whole system should be completely rethought. Instead, we're pouring billions into single occupancy vehicles, when we should've been pouring billions into high speed rail, subways, etc.
I'm hopeful that waymos converge on a more efficient design and improve cities in general. As it stands, they are a way for the rich to commute without having to exchange pleasantries with the underclass.
13X is way more impressive than it seems at first glance.
Let's take a simplistic model of accidents: that the average driver is at fault in an accident 50% of the time. So a perfect driver would only halve the number of accidents -- they only eliminate the accidents where they would otherwise have been at fault.
But Waymo's numbers are better than the "perfect" driver above. How is that possible? Because in most accidents the blame is not split 0%/100%. You can avoid a lot of accidents with defensive and safe driving.
Most accidents are caused by drunk drivers, distracted drivers, jackass drivers and others, who together still constitute a minority, and there are plenty single-vehicle crashes. 13x improvement over average may still constitute diminished safety for a diligent sober driver.
I just watched a short that said some (all) Waymo drivers are not autonomous, but remote controlled by humans in the Phillipines.
I'm sure it's a combination of both since the latency would mean immediate reactions are impossible, but the presenter raised an interesting point, and that was that the remote drivers are not licensed to drive in the states that Waymo operated in, which would make it illegal.

at this point I trust that they have seen me, know that I'm there, and won't behave unpredictably
