I mentioned earlier on the automatic system for speed control in France, which systematically checks every single vehicle on the road, measures quite accurately its speed and mails you a fine within 48hrs, asking you to pay within 3 days.

The system locates your address using the registration number of your car.

According to national news, a farmer in central France received a fine for speeding (150km/h - the limitation on the highway is 130km/hr) and linked to his tractor!!!! I know that John Deere does wonders but I certainly had not heard of this model!
