Earlier quoted context omitted.
Has that ever happened before in the American or other western legal system? It seems highly unlikely that no one would be assigned blame. Heck, we already have cars driven for us (taxis) and the blame for an accident is attributed to the driver, that wouldn’t change if the driver was a computer, the legal syste, wouldn’t simply shutdown.
Well, it happened in the original article. The driver was not charged with killing someone. Even if blame is cast, in the autonomous future that blame would be upon a company, or multiple companies, whose legal departments will spend great effort diverting the blame onto other people or other companies. No one individual will be charged with killing someone, and no one person will have a death on their conscience.
It really is the same with doctor malpractice, the doctor doesn’t go to jail because their patient died because they made a mistake. Transforming civil negligence into criminal negligence as you seem to be hinting at would be a horrible system.
