The car video is silly as well, the crossing van clearly runs a red light. The big shadow of the light pole in the intersection also makes no sense...
Cars run red lights in real life. Driving defensively requires anticipating it. Anyone expecting them not to is more likely to get in a crash.
The rest I can't speak to.
I feel like the car usecase demonstrates that these models are not really useful for the cutting edge: They produce exactly the kind of in-domain data that already exists in droves. What is needed, and what tesla collects, are the edge cases!
(Now for a startup with zero data, this is of course still useful)
