i find myself in the interesting position of actually agreeing with garysher.

why didnt you just drive off? and what happened before the incident that lead to him "forcing you off the road"? i suspect there is more to the story. there may not be more to it, of course, there are people out there who simply like to pick a fight for fun.

in australia, you could be arrested for what you did. you could be arrested just for having the gun in the car at all. the other guy should be arrested too, obviously, but i dont think many people would advocate that he should be shot.

i think your story speaks of a culture that respects violence as a solution to problems, rather than condeming violence as a problem itself. removing guns is not going to stop that guy cutting you off or getting angry, your culture needs another way of dealing with that. but removing guns would mean that this kind of episode is much less likely to turn into a fatality.
