Want people to obey the speed limit? Pay them.

Parents know that sometimes the chance for reward is a more powerful child obedience method than the threat of penalty. "Clean your room or your grounded" can be less effective than, "Clean your room and we'll go get ice cream.". A recent National Highway Traffic Safety Administration study shows that when the stick is combined with the carrot, drivers behave much better. The study placed GPS trackers to measure speed in eight cars loaned to 50 different drivers for a week each. The drivers were told that, at the end of their week, if they kept their speed within the posted limits, they would be paid $25 each.
