The site is to get people more familiar with the cost of a used car that is capable of having a much better ADAS experience using hardware that has no subscription and uses open source software(https://github.com/commaai/openpilot). The site also links(if you click on the detailed support specs btn) to opendbc.com which has other fun data like longitudinal reports(if available) about the specific car you clicked.
In Show HN: I built a site to find cars compatible with open source ADAS software
"Open source has always worked on a system of trust and verify" Not sure about the trust part. Ideally, you can evaluate the change on its own. In my experience, I immediately know whether I want to close or merge a PR within a few seconds, and the hard part is writing the response to close it such that they don't come back again with the same stuff. (I review a lot of PRs for openpilot - https://github.com/commaai/openpilot)

When Consumer Reports tested ADAS systems in 2020 [1], they gave their highest rating to the Comma Two. I'm sure it's only gotten better since then. I really like my 2017 Chevy Bolt except that it doesn't have ACC. I wish I was comfortable installing a Comma on it, but it requires a gas pedal interceptor [2], and I'm not willing to do that to a car that I transport my family in.

In Comma openpilot – Open source driver-assistance
That's not completely true. https://github.com/commaai/openpilot/blob/master/docs/SAFETY... It's an... interesting approach, They essentially reduce the surface area as much as possible. I don't buy that it's enough, but, again, interesting to see what they do. Besides, a big OEM could pour an army of developers and turn the Comma approach into an ASIL D, it would be quite a lot of work but within the realm of possibility.
In Rivian Unveils Custom Silicon, R2 Lidar Roadmap, and Universal Hands Free
Well, that's a bit of my time gone (re)looking into GeoHot, patent trolls, and now comma.ai. Comma.AI by George Hotz sounds very interesting, it's basically a $999 "comma 3x" smartphone with an OBD-II connector and a $99 wiring harness that can add an equivalent of a Tesla Autopilot to many cars manufactured in the last 10 years (even Tesla's own cars, too), for a total cost of $1098, whilst being OSS and available on GitHub, and — get this — even having ssh access to your car! Optional cloud subscription plans are $10/mo for your own SIM, or $24/mo with bundled cellular data. Sadly, it does NOT have an equivalent of Tesla Sentry Mode yet, https://github.com/commaai/openpilot/issues/29912, which is kind of unfortunate, because Tesla's own implementation of Sentry Mode is using 250W of power — depleting the entire 80kWh battery from 80% t

o 30% in like 7 days (".5*80kWh over 7 days" = 238W) — openpilot would have been a nice alternative at what'd presumably be around 5W or less ("40kWh / 5W" is 333 days).
In I couldn't submit a PR, so I got hired and fixed it myself
You mean FUD like THIS IS ALPHA QUALITY SOFTWARE FOR RESEARCH PURPOSES ONLY. THIS IS NOT A PRODUCT. (from https://github.com/commaai/openpilot/blob/master/README.md) > I might or might not have fallen asleep one night on a long road trip and awoken to my car driving along happily My nightmare is getting smashed to pieces by people like you and your insurance refusing to pay because you found it funny to fiddle with your car. You being bankrupt will not help me.
In Happy 10k Day
For those similarly curious, I went sniffing around the PRs and found that, yes, there are two .onnx (via git-lfs) in https://github.com/commaai/openpilot/tree/v0.9.7/selfdrive/m... - one for the forward camera and one for watching the driver. The driver one had a lot more features than I expected, but I'd guess they are related to the NTSB certification I saw mentioned elsewhere in the thread here. Regrettably, because I don't have a Panda-compatible car, I actually can't try out the self-hosting setup but it certainly seems plausible Also, while poking around, I saw they use a "CTF" for on-boarding new contributors, which I thought was neat: https://github.com/commaai/openpilot/blob/v0.9.7/tools/CTF.m...
In Openpilot – Operating system for robotics
> It did some weird things like if the car in front of you was driving a bit too far to the left/right of a lane, it would copy them Wouldn't that conceptually be the right thing for the software to do, copy the human in front of it (unless it has demonstrably better information)? OT1H, "lemmings," but OTOH unless the whole line of cars were all on openpilot my life experience has been that the person in front of me by definition has more visibility than I do since their car is not blocking their view as it is mine I am totally talking out of school, because I'm not in that space and my poor BMW chose to do its own thing[1] so it doesn't work with openpilot[2] -- although they have a dedicated #flexray channel[3] so hope springs eternal 1: https://en.wikipedia.org/wiki/FlexRay 2: https://github.com/commaai/openpilot/issues/44#issuecomment

In Openpilot – Operating system for robotics
The interface between the openpilot and the car is a standalone device (the panda) that provides and enforces the safety model. All code is written in C to automotive safety standards including ISO26262, ISO11270, ISO15622, and MISRA-C. 100% line coverage for all safety unt tests. They also run pretty extensive tests (regression, unit, hardware/software-in-the-loop, mutation, and vehicle specific) on every commit and have actual hardware devices continually running real routes looking for regressions. https://github.com/commaai/openpilot?tab=readme-ov-file#safe... https://github.com/commaai/panda?tab=readme-ov-file#code-rig...
