Most of the world doesn't have 6x6 lane uncontrolled intersections where people need to yield to the right. In fact your average 2 lane intersection with traffic lights, here in North America, once those traffic lights don't work for some reason it becomes almost impossible to navigate the intersection despite the "priority rules" being more or less known. It just becomes total chaos because there is usually enough traffic to just keep one direction going forever given that everyone slows down.

Even with one lane intersections North America usually uses "all stop" if there's any amount of traffic to regulate the flow.

I just hate multi-lane roundabouts in general but the French ones I dislike even more. There's a lot more that you need to keep track of, the traffic in the roundabout and the traffic that wants to enter.
