I'm afraid they've arrived with avengeance in France.
A warning to everybody who likes a blast down to Le Mans or wherever, there is no tolerance on these cameras, 91km/h in a 90 zone will get you a fine (90€ I believe) and being found in posession of a radar detector may lead to your car being confiscated:eek: . I'm trying to find if devices such as Road Angel are legal, but am currently keeping mine out of use. I personally won't chance it without a letter from a French lawyer stating that the device is legal.
Oh well... off to Germany and its Autobahns.
PS (edited on afterwards) Posession of a radar detetctor recently got a driver 4 days in jail as well) I can't warn you any more than that, unless they bring back the guillotine!
