You think round-de-bouts are bad. Wait untill you see this.

After looking at the video, if people use those Michigan traffic circles as they should, by entering in the proper lane, everything should flow smoothly.

It has been many years but I recall some of the really big round abouts in England being over 4 lanes wide & speeds around them could be 45mph.

I'll give something else to the British, their roads are signposted far better than America.
