Having driven in both, Americans don't take naturally to roundabouts and it would be difficult to teach all the existing drivers about them. Same in the UK when they add new rules: most drivers remain completely unaware of them.
There’s nothing complicated about roundabouts: entering it is like joining the traffic from a parking lot/your own driveway, exiting it is like exiting a highway.
