I know you know UC Davis and the town of Davis

any way...roundabouts all over the city and also on campus........

should watch the campus round about around noon as classes get out and thousands of bikes converge upon them...some going 20 MPH others try to figure out how to enter going 2 MPH ...... it gets ugly when they try to leave the inside circle and are either trapped or get nailed leaving. Accidents galore.

I do agree it works well with cars, although I am always careful as many dont know how to use a round about
