n traffic circle; rotary. The device put into the road as a snare for learner drivers and foreigners. Everyone has to drive around in a circle until they see their selected exit road, at which point they must fight through the other traffic on the roundabout in a valiant attempt to leave it. Roundabouts do exist in the U.S. (predominantly in Massachusetts) but in the U.K. they’re all over the place – there is no such thing as a four-way-stop.
