I often ride around town on my Kogswell D50 and last year a driver "buzzed" me during my ride. I wasn't hurt but a police office was sitting in the parking lot on the other side of the road and witnessed what happened. The office pulled over the driver. I didn't stick around, just kept riding. But justice was served, don't you think????

Another time I was riding in a peloton of approximately 30 riders and a driver in a pickup ran a couple of us off the road and screamed at us. Several of the guys decided to chase him to the next stop light. They caught up with him, knocked on his window to explain things. He eventually rolled down the window and he agreed he was in the wrong (maybe it was the intimidation of being surrounded).
