I don’t think they segregate their training data based on car models. I mentioned in an above comment, but Comma.ai doesn’t do this and their devices support tons of cars. It would be very odd if a company far smaller than Tesla was able to figure out how to account for different camera positions and Tesla wasn’t. I bought a 2022 model year car and plugged the Comma device in and it just worked, and they would have had pretty much no training data from my car at that point. Just my speculation though.
