Exactly this, or something very close to this already happened in history. There was a time it was legal for pedestrians to just walk on the road. Now it is illegal and nobody blames "killer bolt" or it's operator if this person is hurt. Society adapted around technology, not the other way around. The other example is of course railroads and trains. People literally made laws and diminish freedoms of people to allow giant polluting noisy hazardous carriages do their thing and punish anyone who impeded them harshly. No reason to think it can't happen third time. We just adapt roads, laws and customs to tell people e.g. "if a purple vehicle on purple road kills you, it is 100% your fault because this law says so". And other nations will have to accept it too because nobody wants to be outcompeted.
