If I was stopped at a crowded intersection, and for some reason, this guy got the drop on me (I either didn't see him coming, or didn't prepare for him), then it is probably to late to do anything in way of force. I would honk my horn, flash my lights, and, if necessary, back into the guy behind me. Draw as much attention to myself as possible. If the BG wants to kill me, there is not much I can do, but at least everyone should have seen what he looked like, and what he did. Hopefully, he will realize this and get out fast. If I am not in a crowded place, then I'm gone. Let him try to hit me then. Or I might try to run him over (not really).
