I think a small enough rate of mistakes by Tesla el al, is not a huge problem, considering the technology is promising to substantially cut the fatality rates.
My question is about liability, if a person is drunk or high and they drive over someone, they go to prison. If a person is sleeping in a tesla and runs someone over because they think it's magic and will drive for them, who is responsible and will do time?
Your reply is that it's all good because the tesla only killed half the number of people, so your friend or family member who got killed is just a freebie.
If you are able to link actions of an individual to an injury in a jury-proof way, then sure I agree it should be done. It's likely not possible in most cases.
