If one of their autonomous vehicles kills somebody while running a red light, it could well be the end of Uber. Kalanick should probably be fired at this point.
I really doubt anything criminal will be brought against Tesla, but it at least sets a precedent for an investigation. Considering Uber's complete refusal to follow regulation, it seems you could argue they're being negligent and if someone dies that might be interpreted as manslaughter (I am not a lawyer). At the very least, I'm sure it will be a PR nightmare and a huge court case that would put a chink in their armor.

Why isn't Tesla finished after their extremely negligent death?
The first automobiles killed many people and have continued to do so in ever greater numbers. I think everyone knows we're going to have some deaths moving to computer controlled cars but that the price is worth it.
