French treasury The french treasury is supported by a huge amount of speedcamera's, of course, not even deployed to enhance public safety, but simply to keep the money into the coffers flowing.  Consider this: France has, with EU money, set up a network of interlocking highways. These are well serviced. The difference in price of petrol here is glaringly visible. 25 cents per liter difference is nothing. But, to make the exploitation even better, the highways are build as toll roads. To drive through France from North to South, easily costs a 100 €. One way. Which means, for French reg plates, on top of the usual road TAX, there is the toll.  And if you fail to adhere to the max speed, which changes very often, you get the privilege of paying an administrative fine. For Europeans, this is an automatic process. France is connected to all numberplate regs.  You get the ticket sent to your home, you pay first, by banktransfer. Then maybe can deny. At any rate. < 10 km/ h speeding ticket will cost 45 € per photo. At least when you want to take advantage of the early pay discount. For instance, on the road from the border with Luxembourg to Dijon, you have easily 80 camera's. That's only 500 Km's. So every time I would drive there, yep, within a week, I had my ticket in the mail.   It is reported that now, half of those camera's have become out of order by force. It seems both sides of the divide are upping up the ante. added:  To put it in the perspective of money: In 2018 the French will have collected about 900 million Euro's in fines.
