I caught up to him at the next traffic light, knocked on his window, politely reminded him of the 3 foot law, explained that it he frightened me by coming within about one foot instead of obeying the 3 foot rule and requested that he follow it from now on. I bet he remembers that and will maybe share that experience with family and friends. (He reacted to me impassively.) Regardless of the attitude with which he talks about the incident, every time he mentions it, it will draw attention to the law and raise awareness. Conversely, I try to obey traffic laws (red lights, hand signals, etc.) and every time a driver gives me the right of way I respond with a smile and a friendly thank you wave. If the window is open, I usually call out a thank you.
