Worked at Stanford when Clinton was president (95-98). Bicyclists would come barreling through the pedestrian areas of the campus with no regard to others. Once, while on the way to the campus PO, two cyclists collided. One was about 5'6" and the one that was at fault was about 6 ft. Neither one had visible injuries, but the shorter guy grabbed his bicycle pump and started savagely waling away at the other guy's bike. The crowd applauded him after it was over.
