A couple of years ago I had an encounter with a driver where I, while pointing/talking with him, tapped the passenger side window as he rolled it up. This was the result of him racing up to my wheel then, passing me very closely while shouting that he would "run my ass over" the next time he saw me on the road. I asked him to pull over to discuss, he instead rolled up his windows and drove away. I called the cops who later advised me that, even though he threatened my life with his car to initiate this argument, had I "banged" on his window (and I didn't even remember it at that point), I could be charged with assault. As if the two are equal and off-setting penalties. I told them that it's as though someone were pointing a gun at me and by tapping on the barrel I'd be equally at fault. They never charged him and, I tried to do a citizen's arrest through a magistrate but, that was denied.

While I know your frustration you should consider my incident as well as the likliehood that he might later take aim at you with either his truck or, a gun. Your goal as a defensive rider/driver should be to get to you destination safely without injury/death. Hope this guy learns from this and/or you never encounter him again.
