roundabout VS 4-way

http://www.wimp.com/testroundabout/ My only problem with the video is that they imply we don't have roundabouts here in the US. We do, they just aren't as common as 4-way intersections. In my town, a 4-way stop was converted to a roundabout. Some people are still confused by it (stopping when there's no reason to), but it has helped tremendously.
