I live in a modest size town in missouri and we have three round abouts. They are on s pretty popular road and work quite well to keep traffic flowing and letting people get to where they want to go. Most people are fucking idiots about them though and they become death traps when icy.Swollen Goat said:I live in the US. I was suprised to hear that they exist over here-there's certainly not any in the midwest where I am. They do seem like they'd lead to a smoother traffic flow, though.
edit: I have never seen a two lane one though. that would mess me up.
