I would let it go. I've had my share of run ins with ah like that, just shake it off I guess. I had a guy drag his minivan down my bar end after I safely pulled over and stopped to get him off my a**. Pulled up next to him at the red light, we exchanged pleasantries, he put it in park and I hammerfisted his mirror off and went about my way. Could I have called the po po? Yes but I got more satisfaction from doing what I did and I safely got away and never saw him again. So don't let it discourage you from riding, cbus just sucks and people around here don't care.
