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.

hahahahhaah•54m ago
I like Comma. I like geohot (I wouldn't want to work for him I imagine it is intense) but I like the contrary attitude and also the product as seen as demoed on youtube.
smallerize•41m ago
He hasn't been running comma.ai since '22, and even left the board just in November.
hahahahhaah•22m ago
sorry not been keeping up. thanks for the info
rvz•18m ago
He (geohot) is still the President of Comma.ai and still owns the majority of the company.
smallerize•5m ago
His LinkedIn says he stopped being president in November. https://www.linkedin.com/in/george-hotz-b3866476 I haven't seen any other news about it.
ab_testing•50m ago
How is the experience on the Corolla. How much can it do by itself?
mbirth•25m ago
What a coincidence, LTT tested it a few months ago in a Corolla. Here’s the video:

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!
Der_Einzige•1h ago
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.

androiddrew•1h ago
I know george hotz was the CEO. Who is it now?
smallerize•7m ago
They don't have a single person listed as CEO. It was Ricardo Biasini for a while. https://techcrunch.com/2022/11/02/george-hotz-aka-geohot-is-... More recently he was part of DOGE. https://therevolvingdoorproject.org/riccardo-biasini-doge-ag...
nullfish•1h ago
geohotz, the infamous person who cracked the PS3 at the time. Been following him since that time and this project since he started it. His blogs have always teetered on the edge of unprofessional while remaining incredibly knowledgeable and insightful. Truly enjoy all his work.
CursedSilicon•1h ago
Minor correction. Geohot never cracked the PS3. Fail0verflow did.

Geohot watched their talk. Rushed out a "hello world!" jailbroken firmware based on their talk and got the team in massive legal trouble for doing so

nullfish•1h ago
ah that's right, thanks for correcting.

still, I think my other remark about his writings stand.

Rebelgecko•1h ago
I assumed he was a Musk disciple after he took a sabbatical to help with the twitter transition
billisonline•37m ago
I assumed that too and wrote him off. I’ve since changed my opinion, especially in light of this blog post: https://geohot.github.io//blog/jekyll/update/2026/01/18/how-...
kyle-rb•11m ago
I would write him off less if he had shipped even one thing during those 5 weeks he spent at Twitter when he promised to "fix search".
plun9•19m ago
He has commended Tesla Autopilot many times and has stated that their technology is much more similar to Tesla's rather than Waymo's.

julianeon•1h ago
This is awesome. I hope this technology continues to advance and decrease in price - but it's already a great value at this one.
sergiotapia•1h ago
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!

FAQs including - What is openpilot? - How does openpilot work?

at https://comma.ai/support#what-is-openpilot

zie•1h ago
Generic Openpilot out of the box is just super nice cruise control right now. So it can do longitudinal and latitudinal control. So it lane keeps, stays behind the car in front of you, etc.

If you use Sunnypilot or one of the other friendly forks, you can do more, but it's not (currently) to the state of Tesla's FSD.

Personally, I recommend buying it if you do a lot of road trips. It's amazing for that. In/around town it's only useful if you have a lot of stop and go traffic, like if you live in LA or other large car-centric city with a big commute.

guyfromfargo•1h ago
I have one of these and I really enjoy it.

No it’s not FSD. There is no navigation at all, you’re correct that it’s “just lane assist”. But the lane assist is next level.

I take a few 1,000 mile plus road trips every year and the comma pays for itself every time. Using the stock lane assist, I’m constantly correcting it. The stock assist tries to take an exit, doesn’t handle curves well at all, and any construction or unusual road conditions it won’t work at all.

With the Comma, on the highway it’s basically FSD. On my last 1000 mile trip I never had to disengage, only to pass and make turns.

The biggest advantage is Comma allows you to be completely hands off the wheel. Where lane assist forces you to hold the wheel at all times.

geaibleu•7m ago
I still use old comma branch running with OnePlus phone on Subaru. It works really really well, even on snowy northern roads. The code, from firmware C to python is very well written as well, makes it easy to tune it to your driving habits.
Mountain_Skies•1h ago
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.
testfoobar•1h ago
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?

hahahahhaah•55m ago
I guess it would be like open source cruise control. In that they could assert some probability of incorrect installation that caused the accident.
wing-_-nuts•52m ago
I mean, just like with a Tesla, the driver is responsible for the actions taken by the car, which means you do need to be paying attention, hands on the wheel, ready to take over at all times.

We don't yet have the legal framework to say 'Sue company x, it wasn't my fault!' You get sued, then you have a very uphill battle to turn around and try to sue the company that provided the 'self driving' functionality because companies put all sorts of 'I totally accept liability for using this' in the T&C of their products.

sitharus•43m ago
At the moment in every jurisdiction I’m aware of the driver is always considered as “in charge” of the vehicle no matter what assistance functions are being used. It’s the driver’s responsibility to avoid collisions in all cases.

If you have a collision and your vehicle is judged at fault by whatever authority does it in your area the you are liable.

charcircuit•40m ago
What if there is no driver because the car is self driving?
gegtik•37m ago
I assume the same as if the car owner put a brick on the gas pedal and there was no driver when it had an accident

Found the Chief Legal Officer for Waymo
sitharus•27m ago
Well that will depend on your local laws, but to my knowledge except for certain authorised pilot programs all cars on the road must have a driver.

Where I live if you are in the driver’s seat no matter if you were actually actively driving you are considered to be the driver. This has been well established here in drink-driving cases, but you’d have to ask a lawyer for your area.

digitalPhonix•22m ago
Mercedes Drive Pilot (“SAE Level 3”) is certified on some very specific stretches of insterstate in California to not require the driver to be responsible.

https://www.mbusa.com/en/owners/manuals/drive-pilot

Requirements:

- Stop and go traffic (or less than 40mph?)

- On some specific sections of highway

- Driver doesn’t need to monitor but must be ready to take over with 15(?) seconds of the system requesting

> Mercedes-Benz is assuming liability for any crashes or incidents that occur while the autonomous system is active

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.

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.

> 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?

CamperBob2•10m ago
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."

rvz•22m ago
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

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.

bad_haircut72•15m ago
Nobody is making you do this, they're not even charging you for it. Comparing to a company worth billions is disingenious.
tokyobreakfast•4m ago
Those companies worth billions like GM and Tesla perform extensive testing to prove to regulators their software isn't going to kill people.

How do you control if someone else does this?

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.
