My buddy Gil was struck by a 2x4 that was being carried in a car with about 3 feet of it sticking out the window as the old geezer passed him. Gil was an off duty cop at the time, and when he picked himself out of the ditch, he hunted down the vehicle (it was a rural area with good visibility for parked cars). He found it, went into the guy's home, interviewed him, the guy denied knowledge of having struck him. Gil performed a citizen's arrest (he was out of his jurisdiction) and the old geezer eventually lost his license for being too incompetent to drive.
Once, I had a guy in a VW bug try to touch my rear wheel with his front bumper while we were both moving down the road! He was so close, I could not see him in the mirrors! When I sensed something was close behind me, I turned my head in time to see this guy peering intently over his steering wheel at his front bumper which was then about 6 inches from my wheel. Needless to say, I gave him the international sign of ill will with my left hand, and twisted open the throttle with my right.
Dang! Motorcycles are dangerous .... or is it stupid people?
