Comma is my favorite “AI” company. Really incredible piece of tech in a tiny package, and it truly improves your life to have it.

I wish it worked with my Mitsubishi Outlander, but just having it on my Corolla is enough. Their supported brand list will definitely factor into my next car buying decision.

Ran into this a few days ago while looking for a way out of the subscription hell of self driving offerings. Very excited to watch this space!
The CEO of comma.ai is an absolute class act and is basically the anti-elon musk.

Comma is awesome, and more companies should be like them.

Still hoping Opel will be covered
This is awesome. I hope this technology continues to advance and decrease in price - but it's already a great value at this one.
The thing is, none of this is really better than any of the simpler systems in terms of use.

If you are required to pay attention most of the time, it defeats the purpose of self driving. Most humans can perform very complex tasks while keeping a car in lane, and adaptive cruise control is nothing new.

Also, being in my coworkers/friends Teslas that are using Autopilot, it almost seems like there is more cognitive load in using it in crowded areas, because you have to be very attentive to catch a disengagement.

I was in the market for this for my Pacifica but I couldn't figure out what this does exactly.

Is it FSD basically?

Is it just lane assist?

Can I put an address in a map and it takes me there?

Very hard to just get these concrete answers, maybe they just take the newbie experience for granted and assume people know these answers. Anyone who owns one of these can answer? Thank you!

Wonder if it will be able to work with the Slate pickup when that comes out. Seems like it would be a perfect pairing if the Slate has enough control exposed to it.
Really impressive tech. I don't understand the insurance ramifications of installing and using this system.

Comma's website links to a 7 year old reddit thread: https://comma.ai/support#will-my-insurance-cover-my-car-with...

As a driver, if in an accident, could someone reasonably assert that you were not paying attention?

In an accident, culpability cannot transfer to a computer ostensibly running under your supervision. As a driver, you likely sign away all claims to blaming CommaAI when you accept the EULA & ToS updates.
No, Comma has best in class driver monitoring
When one of my coworkers bought a used car, he went out of his way to buy a model year that was compatible with Comma. He has lots of praise for it.
Are they still being extra and only asking about Putnam scores during interviews?
Seeing things like, "<h2 id="new-driving-model">New driving model</h2>" on their list of latest releases does not inspire a lot of confidence. Yes, the HTML tags are displayed on the page. Some basic quality assurance on the website would help me trust the quality assurance applied to their product offering.

I'm supposed to entrust my life and others' to this and they're bragging on their home page about GitHub stars?
It’s open source bro, just read the code if you don’t trust it.

/s

That said I am intimately familiar with the code and it’s pretty well designed with safety in mind. Plus your vehicle has safety parameters that limits the ability for the software to do something insane. That said there are a few stories of open pilot running into a curb, hitting a car in the neighboring lane, etc

There's a few Lex Fridman podcasts with George Hotz, the founder. Highly recommend them:

No idea how Fridman manages to bring on the type of high profile guests that he does. Guy does not ask good questions and has the charisma of a wet rag,
These are really just ramblings, nothing of value is being said.
> Currently, openpilot performs the functions of Adaptive Cruise Control (ACC) and Automated Lane Centering (ALC). openpilot can accelerate, brake automatically for other vehicles, and steer to follow the road/lane. [1]

[Some of the] Cars that are currently supported already have "smart cruise" and "lane follow". Why then use a third-party self-driving system?

[1] https://comma.ai/openpilot#:~:text=Currently%2C%20openpilot%...

I have a car with smart cruise, but there's plenty of room for improvement. It isn't very smart at determining when it can avoid braking, such as when a car well ahead has slowed for a right turn. It also brakes too aggressively when someone cuts in front of me on the highway, in situations where just lifting off the gas would be better.

It also times out very quickly when traffic comes to a complete standstill, requiring manual intervention to get going again, and it doesn't give any indication to the driver when that occurs.

If these things bothered me much more than they do, I'd be interested in comma.ai as a possible solution. As it stands, the OEM radar cruise control is "Eh, good enough, I guess."

Maybe this doesn't beep at you if you take your hands off the wheel?

And people think that is a good thing?

It's infinitely better than HDA2 at tracking and maintaining lanes.

HDA2 cuts out if there is a break in lines more than 50ft or so.

Openpilot can track the slightest of roads, even able to follow off-road the tracks in grass from a leading car.

It does basically everything HDA2 does and then some, and does it much better.

It has a driver-monitoring camera that you control, that monitors for inattentiveness which is much more effective than simple wheel-torque based sensors.

I wondered the same thing but after trying a few oem attempts, there’s definitely huge room for improvement. Lane following isn’t very ‘smart’ and doesn’t take context into account (ie. changing position in the lane based on clearance from other vehicles, potholes, upcoming curves etc.)
Lane follow? Does it have lane discovery? There was snow on my commute this morning. 4-land highway was basically follow the leader. Pick some line where you think there is the most traction and stick with it. I have yet to see footage of an autodrive system in such a situation.
Commercial implementations back when this launched was vastly inferior to it, if users' accounts are to be believed. Obvious signs of too high P in PID and such.

Tesla Autopilot was always available, but they were as sketchy as it always had been. Shoving the head into road barriers and fire trucks with rear ends that were less car looking especially to pre-LLM image recognition models.

OpenPilot also allow retrofits. People who own 2017-2023ish cars, shipped between the times after self driving hype took off and before command signature enforcement was widely implemented, can DIY self driving without re-buying the whole car, put aside whether it's legal or whether you should.

Top voted comment on hacker news btw.

Ok that was probably unnecessarily snarky I hope you don't take offense, but it seems the hacker spirit has been fading more often from this site, we used to replace stuff with inferior versions just to see if we could.

Big one, because all those cars require you to touch and move the steering wheel every X seconds. All the ones that let you go hands free cost a subscription of around $500 a year (Ford BlueCruise, GM SuperCruise). And even those only let you use hands free mode on pre-mapped roads, typically only interstates.

Becasue most cars with lane follow still lose lock on the lane when the lines are hard to see (rains, snow, etc) or missing due to exists and other things.

Becasue most cars with lane follow fail to keep well when the turn gets too sharp.

Comma.ai lets you go completely hands free with no wheel nags. It also works just fine when there are no lane lines or poorly visible lines. It also supports lane change by signaling, and then nudging the wheel when it's clear to move.

There is also an experimental mode which stops and goes at stop signs and stop lights.

If the driver monitoring camera in the comma detects you fell asleep or something, it will slow the car down and pull over. All the stock lane keep that I have used in cars, if you fail to nudge the wheel they just disengage and you keep going at full speed in a straight line...

Then we delve into OpenPilot forks like SunnyPilot that let you do things like decouple gas/break control from steering control, so you can control the gas/brake yourself and let comma just always steer for you. Comma can also steer more aggressively in turns than any lane keep I have seen, and when it can't you will see the limit being reached on the little display so you know you will need to help out on that tight curve.

Experimental mode isn't the best all the time, and SunnyPilot allows hybrid mode which uses regular mode and dynamically switches to experimental mode for stop signs and stop lights.

With SunnyPilot it can even read your car's blind spot monitors to automatically make the lane change hen clear without you having to nudge the wheel.

Some have been playing with concepts of auto navigation too where the car will take exits and turn through intersections for you.

The comma.ai devices have 10W of compute power and the current driving models only use 1W, so there is room to scale to better models with teh current comma devices. There is also talk of supporting more cameras for side views and external GPUs addons with 100W compute for potential FSD level models.

(comment deleted)
I've been using comma 2 and now 3, for over 5 years and its my most favorite thing that I own. I would never buy an incompatible car going forward and got my tucson 2024 specifically for use with comma. I did once think I really wanted a tesla but I realized I just wanted self driving. I routinely tell everyone about comma + openpilot and am surprised I've never seen another driver on the road with one. People are still mostly in the stone age with respect to driving. Granted I think you are always solely responsible for your car when behind the wheel and should only treat it as an assistant but it sure does make driving chill.
8 years later, comma.ai is still standing and operational despite several VC backed competitors raising significantly more than Comma and those competitors (except for Tesla) are now no longer in business.

People here have no idea they are looking at a robotics and AI company which that is Comma.ai

This runs with just a single front-facing camera?
Looks like there are 3 cameras on the Comma 4. There's a narrow FoV camera facing forward for distant objects.
Depends on the car what it has access to. It may leverage radar data, for example. Some cars (Ford Lightning for example) it only does lateral (steering) control, longitudinal control is still under the control of the OEM adaptive cruise.
3 cameras. Front facing 180 degree, and front facing telephoto. Rear facing 180 for driver attention monitoring.
I read at least one thread per day criticizing Tesla self-driving (which has hundreds of highly-paid engineers working on it) as unreliable vaporware, meanwhile I'm supposed to hack my car with some code off a GitHub repo?

I'll be adding this to my list of 101 creative ways to die, behind basement apartment in Venice, Italy.

Creating an open source project makes a space for collaboration.

There is a future where every manufacturer shares the same self-driving software.

You already trust your privacy and financial security to open source projects. There is a future where you also trust it for a self driving car.

Are you really expecting me to read this paragraph all by myself? What am I supposed to do, load some text off of a Hacker News comment section? I only read paragraphs written by teams of highly paid experts.

My thoughts exactly.

This is a horrible idea for a bunch of reasons.

Real driver assist systems are tested for each car for millions of miles before release.

I can imagine this as a toy on a recreational vehicle like an ATV, but it's outright reckless to put this on a real car.

Tesla FSD is awesome. I use it almost all the time now, it feels safer than me driving. It's like having a private chauffeur. My disengagements are mostly nav related.
there is also sunnypilot, which is a fork of openpilot, and supports more behaviors and cars: https://github.com/sunnypilot/sunnypilot
What's different? From the README I only get that it's trying to match comma's safety as closely as possible - whatever that means
Can someone with technical knowledge explain the key differences between the assisted driving technologies used by Waymo, Tesla, and comma.ai?
Huh, no love for the Toyota bZ / Subaru Solterra. I wonder if there's a reason or if just nobody's gotten to it yet. (It does have good built-in ACC.)
OEMs would be smart to donate money to this
Will this be deployed mostly by those with the worst judgment?

For example, that video is implied to be of some open source self-driving project, run on an active public road, at 42mph. A lot of sensible people would say that's irresponsible or unsafe, and not do it. Move-fast-and-break-things bros and narcissists, however, wouldn't see a problem.

I'm sure the technology is great, but what would be really great for me to use theoretically use it would be for it to be if the company was liable if it caused an at-fault accident. I don't know much about the law around this, but I comfortably get in a Waymo all the time because I have some intuition about it that tells me that their lawyers are scared shitless of killing someone. It's a hard sell for me when it says "self-install at your own risk" but I appreciate the effort.
It’s NOT self driving. It’s level 2 driving assist. Really good one, but that has nothing to do with self driving. You are driving the car all the time, it’s only assist that can (and will) try to kill you (and others) with 0 notice if you don’t pay attention.
