In France until fairly recently the rule on roundabouts was for traffic on the roundabout to give way to entering traffic. Sheer madness. In the UK we've had loads of roundabouts for years and we're well used to them. Of course we drive round them the correct way. Unless those in the USA

I don't know what the guy who designed it was smoking but it must have been some seriously nasty stuff.
What confuses us in the USA is the 4 way stop. We get a little taste of it on very small roundabouts here in the UK (usually 3 way rather than 4) where everyone is stopped and wondering who should move first.
