There's a roundabout near my house that I'm forced to circle regularly. I enter the circle with fear every time because I never know how close to an accident I may come that day. The other day I was cut off by a BMW traveling the entire circle in the outer lane when it occurred to me -- how would anybody in this country understand how to use a roundabout when there's nobody teaching it? If you are among the many who don't exactly understand the great traffic circle, check out this quick tutorial on how roundabouts work
along with a long-winded monologue on traffic signals and roundabouts in history.
