A couple of months back I called the cops on a driver that buzzed me really close with his van (he was texting or doing something with his phone as he passed) and I patted his van with my mittened hand as he crossed over in front of me almost pushing me into parked cars. When he heard my "thump" on his van he slammed on his brakes and burst from the van screaming at me to get out of the road, I had no right to be there etc. and came at me. Fortunately, he stopped short of taking a swing at me and despite his foul mouthed diatribe I managed to keep my cool as I attempted to explain my right to be on the road.
He continued to harass and threaten me and said he drove that route often and would get me next time he saw me on the road- that was enough for me and I called the cops. He waited for them to arrive(!), they took his info, gave him a brief lecture and off they went. As they got back in their vehicle I thought he was flashing me a peace sign but it was the universal two fingers to the eyes of "I'll be watching for you."
I haven't seen him since- but I admit to watching for him every day.
