In a move that would piss Americans off, the French will be using a satellite to track the speed of vehicles they detect. They will monitor vehicle speed via a satellite via an installed sensor. If the satellite detects the vehicle is over the speed limit they then electronically reduce the fuel flow of the vehicle to slow the vehicle down.
Can you imagine what most Americans would say if the Government made a such a move. The hand writing is on the wall for the citizens of France. [Tribenet]
