From personal experience: "yes, no question", and "maybe though it'll take a long time and a lot of compute and training data". The day level 3 automation (basically what Tesla's FSD is, even though it's classified as level 2) comes to some other car, I'll strongly consider switching.

Maybe a stock crash and total failure of Tesla will be the best thing that happens. The US government (assuming us citizens can somehow continue to claw it back) or some benevolent entity can buy the ML models for cheap and open source them. It's really their only truly valuable, resilient asset, IMO.
