The most recent winners of the fabled 'Cannonball Run' used all kinds of assists to keep them from being pulled over. One of the tools they used was a friend who shadowed them in a light plane to keep watch and warn them of any troopers in the air or around the corner. The troopers in the air will time a car (using the little airplanes on the pavement) and radio another trooper on the ground waiting for the law breaker. The guy on the ground will then just wait for the car/truck/bike/moped to come along and then pull the offending commie scofflaw over.
