Isn't the roundabout at the Arc de Triomphe still priority to the right (ie to traffic joining the roundabout)? I also believe it might be the only roundabout left in France that still has priority to the right.
Well, that depends how you translate "roundabout". Strictly (and there's no shortage of pedants in France) a
rond-point works by
priorité à droite, while a
carrefour à sens giratoire has signs and markings to give priority to cars
déjà présents dans l’intersection. You can drive a long way on roads that go somewhere and never come across any
priorité à droite, as it's been widely suppressed on main roads and in a lot of towns by always having lights or marked priorities. But it is still the default, common in little back streets, and once in a while you find one of those cancelled diamond signs on entering a little town.
But Place Charles de Gaulle is more of a big open space for cars to mill about in (if they are lucky) than a roundabout. I think there will be other, smaller, circular town squares elsewhere that have never had anything added to displace
priorité à droite. But these are not high-speed roads, so disconcertingly unfamiliar rather than downright scary. The lack of stop lines on side roads should prevent you assuming priority - provided you spot it!
