The Magic Roundabout. Famous, even on these shores. When I first saw it, I spent a good ten minutes running my mouse through, seeing how it worked. I wonder what sort of traffic counts the roundabout gets, and what the safety record is like compared to a plain old signalized intersection.
Roundabouts are gaining ground in the United States, but folks have a love/hate relationship with them. We Yanks are used to driving straight and fast, and the folks who despise roundabouts would rather come to a full stop rather than slow down and turn the streering wheel right for a few seconds. We're a lazy bunch.
Growing up in Buffalo, we were blessed with the Frederick Law Olmsted-designed parkway system, with majestic traffic circles that would make even Boston natives cringe. Any Buffalonian worth their snow removal salt loves the circles. Driving south on Delaware Avenue -- you bounce under the stone arch bridge that carries the Scajaquada Expressway over the Avenue, play Formula One driver through the infamous Delaware Park S-curves, bank a hard left at the end of the park to stay on Delaware, and then screech around the Gates Circle fountain. Better than any of the roller coasters at Darien Lake.
By the way, here's something to put the Poms in their place.

Makes me want to go out and topple a dictatorship! God Bless America!
