I don't know if there's a physical port in most cars, but it uses the CAN bus which has been around since the 1980s. Also, most cars that have distance assist and lane keeping probably have the required hardware to control speed and steering to some extent. Nevertheless, it's still impressive that so many cars are supported... and that it can be retrofitted like this at all!

They also lie about models that are supported and won't assist you when you run into that. Had to return one myself. Found no evidence anywhere that my model/year was ever actually supported and anyone was using it either.

  Sounds like they refunded you?

    Yeah, that process at least was painless

      It looks like support was added in February https://github.com/commaai/openpilot/pull/30761 https://github.com/commaai/openpilot/pull/30761

        Yeah it was on the supported list when I bought it in October of 2023. The website asks your make/model/year when you buy if I recall correctly, that's how it tells you which harness to get. I found out I needed to update some files in the firmware, followed the guide for that. Asked for help in the Discord. I could never get it working though and returned it after a week. I was going to hang on to it and harass people on Discord, but didn't want to lose track of time and go beyond the return window. Believe me, I really wanted it to work. Looks like it was added to the supported list before the explicit support I guess https://github.com/commaai/openpilot/commit/e3275e918354945d543b68d5cade56c22d423693 https://github.com/commaai/openpilot/commit/e3275e918354945d...

      > discord is unfortunately not search indexed. Using discord, etc for any open source project discussions is really unproductive. Get it that people like the immediacy of chat style communication. But it seems to encourage way more noise and less thoughtful dialogue. The worst aspect is that it locks away a lot of useful information. Trying to dig through chat histories for information is a horrible experience.

It might not be the best implementation of chat, but the immediacy and lack of formality are undeniably valuable.

  There's a very active community on Discord that would have been happy to help you add support for your car assuming it has the right hardware. https://comma.ai/vehicles https://comma.ai/vehicles has also been improved quite a bit in the past year.

I beleive in the US OBDII ports are required in all vehicles 1996 and later.

I suspect Openpilot sends packages to CAN bus to do steering but what makes the physical wheel rotates? I'm confused. Or when a human makes a correction to auto steering, perhaps there could be some kind of full duplex synchronization mechanism
