My town, Sedona AZ, is experimenting with roundabouts in a major way. Nine of them are being built to replace major intersections that once had signals. One of the first to be completed, several months ago, is right outside my complex. The big advantage: the roundabout is much quieter than the old signalized intersection at night, when most traffic just glides right through. The big disadvantage: the roundabout is noisier by day, when there is a constant chorus of honking as local drivers tangle with tourists who are clueless on how roundabouts work.
Bet you are looking forward to having your town the location of the weekend White House.
Try driving in Europe. In the UK, cars in the round-about have right of way.
on the European continent, right of way is given to those entering the round-about.
Not only are they driving on two different sides of the road, they have opposite rules.
