How about driver vs cyclists? When I was young & stupid, some friends pooled our money, spent all but a few bucks on beer, then went to a drive in movie with 3 buddies hiding in the trunk. We had just settled in when two attendants rode up on bicycles, told us they saw everyone getting out of the trunk & we could either pay up or leave. I started up, put it in reverse & knocked over then ran over the bikes they had laid against the trunk of my car! OOoops, clumsy me. As we drove away, one guy was stomping on his tacoed wheel trying to straighten it out. Since about 1/2 my high school either saw or heard about it, I was now famous & everyone started calling me "crash".
