Stopping on a pedestrian crossing. Take a photograph - see how they react. The last time this happened to me I pointed to the traffic lights as he moved. I watched as he crawled forward, it was not total oblivion to anyone else but the car in front. "Can't see the red light mate"! He stopped for me but I doubt he thought he was in the wrong, just unlucky.
