> If my car runs you over, and you sue me, what does the court do? It tries to figure out my intent. Did I intentionally run you over? If yes, I'm guilty of vehicular assault (not my car). Or did the brakes fail and I had no intent to hurt you? If yes, I'm not guilty of anything.

Or you failed to follow the rules, were careless, and hit him by mistake. Was your intention to kill him? No. Was it your fault? Yes.
