UW-Madison transportation safety expert David Noyce traces the roundabout?s bad rap back to Chevy Chase in the 1985 comedy “European Vacation.” Chase?s character, Clark Griswold, drives his family in an English rental car into the inner lane of a roundabout near London?s Lambeth Bridge. “They got stuck in the circle and couldn?t get out,” Noyce recalled Thursday. “So people had a negative view.” And a lot of motorists in Wisconsin still do.
