Nearly crunched my car near Boulogne with one of the give way to the right junctions. Only HM The Wife's beady eye on my left saw the emerging car first. Then I saw the line in the main road ahead of me. I'll try not to do that again. When the law changed in France about banning radar detectors and sat navs which identify speed camera sites, they included the right to seize the vehicle as well as the device. Not sure they uphold this, but it could make for a pricey and difficult trip.
