> Having to prove yourself innocent of criminal accusation after killing someone else seems like a pretty reasonable system.

I think you have it backward. You are being asked to prove yourself innocent after being accused of being the guilty party in an incident in which somebody died.

> The idea that killing other human beings using a car is "expected" and "the norm" seems to me like the bad system.

I don't know where you got that idea from. Seems pretty deluded.
