Usual highway roundabout. Called so because if travelled through too fast, your car will have the tendency to (a) fly over the outside curb, or (b) if you open the door to reclose or have Suicide doors, if you fall out, the rear tire on the drivers side RUNS OVER YOUR HEAD, thus comitting suicide by automobile.
Jim: i hate suicide circles, they fail.
Joe: For sure, its suicide if you go too fast.
