Unfortueately not the same way as I do!
Re Prioriy a Droite I've not had a problem about when to give way. Don't look for the signs - look at the driver. A driver with priority has a destiny and you ain't part of it. Easy to spot that look if you have cycled in the UK.
More of a problem is when YOU have priority. Its often counter-intuitive that this big truck or speedy car is going to stop just for you. But they do. What they don't like is if you end up dithering too much. Overall France (not Paris which is another country) is superb for cycling. Almost perfect road surfaces, usually given lots of space by overtaking vehicles and they will patiently follow you when there isn't. Its the British tourists you need to watch out for!
Remember cycling is merely the method of getting from a bar-tabac to a restaurant and back again while conveniently reducing the calories and alchol taken on board. Neverthless anything short of the Tour de France is a failure if you don't come back heavier than you went ...
Oh and take a prepay credit card or that Halifax thingy so you can use ATMs and pay for stuff without being ripped off by our Banks with their imaginative rates and fees.
