Human beings need a target for vengeance and hatred. If someone kills your child, you can hate them. If an automated car kills your child, you don't have anyone to hate. Saying that this is about safety thresholds is a distraction from the true human problem exposed by automated cars:
"Which individual will held accountable and risk jailtime if their car kills someone you love, and how can this individual be identified from the appropriate government registries within 24 hours of a death?"
Until this is clearly defined in law, automated driving will continue to be resisted under any number of plausible justifications, and arguing with those justifications will have little effect.
It’s less interesting to me who is registered as responsible, or what process is used to select that person. But if no specific single named individual is registered as personally liable without possibility of corporate liability shield, then we won’t get public acceptance of self-driving cars for a much longer time than could be possible.
If, as the registered person, you were notified about the vulnerability and didn’t patch it, you could be convicted of criminal neglect at minimum, same as a driver who ignores a recall notice and continued driving.
