Well, the most stupid thing about permanent cameras is that once you know where they are, you will slow down, pass and resume your original speed. A new system is now operational overhere on some stretches of motorway, where the average speed is measured and on a 24 hour basis, permanently. (Radar boxes are most of the times not even loaded with a camera). This is actually very effective to reduce the speed in the designated area.
The fact that the car is the target and not the driver is not so serious overhere because we do not have a point system for our licence. The educational effect of the fine is therefore very small. The act will be centrally registered somewhere and after a certain amount of time the file will be erased. If somebody else would have driven my car (actually Wouter sat next to me) it would have been my problem to get the money back.
