Stupid driver day.
Riding down a main street got passed by a semi. He then slid into my lane and immeditely into a right turn lane giving me abot 1 foot of clearance behind his back bumper. Then he stopped at the red light. As I passed him on the left, I punched the door of his truck. The thin metal actually dented in. Had I punched harder, the dent would have stayed and he would have had to explain it to his dispatcher. too bad.
He yelled at me about riding on the (non-existent) sidewalk.
