I’m curious from a technical perspective, but don’t care much about it in practice, especially in the current state that is not safe enough to be a chauffeur, and too boring to keep the driver engaged. Trains and subway are “self-driving” EVs. Build more of these! You can read a book and not run over anybody. For the problem of “idiot drivers” I think driving assists can be good enough. For safety, cars don’t need to drive 100% of the time, they only need to reliably brake and avoid collisions, which is a subset of the self-driving problem. There’s also a lot that can be improved with low-tech traffic engineering. If the US could ban turn on red, and start liking roundabouts, it would significantly reduce risk of serious crashes.
