I’ve heard that traffic circles (i.e. the circular intersections with traffic lights) are extremely dangerous, and that that’s part of why roundabouts have faced so many difficulties entering the US (because the US had traffic circles in the early 20th century and the cultural perception is that circle = dangerous).
There is a cool roundabout near me with stop lights that all turn red at the same time, stopping all vehicle traffic and letting pedestrians go.
