Warning: If you are from Kansas City or Omaha OR if you believe the Nazis developed the roundabout and, in doing so, started World War II, then you won't want to watch this video.
For the rest of you, while this won't be happening anytime soon in a city near you, it should give you additional confidence when standing up to the dogmatic traffic engineers and their rote, untested, arbitrary standards.
