Rewarding Speed Limit Signs

Above is a video from Kevin Richardson (USA) who was the fun theory award winner for 2009/2010 with his initiative 'Rewarding Speed Limit Signs'. The initiative answers the question, how can we get more people to obey the speed limit by making it fun to do? The idea here is capture on camera the people who keep to the speed limit. They would have their photos taken and registration numbers recorded and entered into a lottery. Winners would recieve cash prizes and be notified by post. Better still, the winnig pot would come from the people who were caught speeding.
