America doesn't have many roundabouts because even if you understand how one works, you have to worry about other drivers who don't. But they are a fact of life in Britain. The ultimate roundabout is this one in Swindon that is actually a cluster of roundabouts in one intersection.
The Magic Roundabout in Swindon, England, constructed in 1972, is the most brilliant and at the same time, the most confusing roundabout ever built. The roundabout, named after the popular children's television series by the same name, is located near the County Ground and consists of five mini-roundabouts arranged in a circle. At first sight, it might appear to confuse or amuse new visitors and certainly baffle tourists but once you understand how the roundabout works you will realize how revolutionary the idea is.

A city near me put a roundabout in a few years ago and the uproar it caused was tremendous.
They do make sense, WHEN people know how to use them.
