Round and round.

Apparently we've exported the concept of the roundabout to America.  Many American towns and cities are finding that roundabouts work better than traditional traffic lights at intersections, as well as being aesthetically more pleasing.  So you might ask why the town of Walsall here in the West Midlands has spent an obscene amount of money and caused months of traffic disruption in replacing a perfectly serviceable roundabout with a complex set of traffic lights. Perhaps the Americans could export the idea back to us?
