In Europe, things are reversed, and the roundabout is much more common than four-way-stop intersections. While it has been said before that the roundabout is a more efficient way to handle traffic at a busy intersection, Mythbustersaims to find out the truth.
We'll be the first to admit that roundabouts can be confusing to Americans, but the Mythbusters crew thinks that could be a result of little familiarity with the traffic tool in the US. We were super curious to see the results of this test, and this writer admits to being on the wrong side of the fence when it came to guessing which intersection was more efficient.
