There is one in my city and it is in popular shopping center, so it get a heavy usage out of it. In the center, there is trees and rocks as decorations and designed to prevent anyone from driving over the center. There is other city that have a small (1-lane) roundabout, the center is protected with chain "rope-like" barrier with the sign to drive right.
