Maybe in situations where someone throws a beach ball in front of your car and your immediate split-second reaction is to turn your car into a murder weapon directed at the first "hoodlum" you spot who may or may not have thrown this ball.

That is a complex question. I see both sides of the issue and a lot of grey area between (I'd be shocked if I foresee even 10% of all the things philosophers will consider).

I'll just say that it is an option with some merit. Depending on the technology and the local situation I might or might not be in favor of it.
