I have been to the bay area many times. Bicyclists there are out of hand. They think they own the road. I had a similar thing happen to me in Sausalito. I was turning right into a filling station and of course, I had to cross a bike lane to make my right turn. A whack job bicyclist rode up behind me while I was making my turn and slapped my car, screaming at me to get the F out of the way.
I saw the same thing happen in SF on Columbus St.--Traffic was heavy and a militant biker rode up behind a pickup and banged his truck. LOL, the driver got out, knocked the moron off his bike, picked it up and threw it in the back of his truck and drove away leaving the asshole biker whining on the side of the road.
I live around there. You are 100% correct!
