The larger roundabouts are "circles" in D.C. DuPont Circle (no pun intended), Scott Circle, etc. They are good at increasing speed through an area and also good at directing traffic across town. However, they are very confusing for those who don't know their way around and in high density traffic can be dangerous.
In D.C., the configuration of most of the circles renders the "increasing speed" portion of their raison d'etre inoperable, while decreasing the danger.
