Oh, Walter... you don't want to know...
We might need an exorcism or something.
I've thought that a traffic circle where each high-volume incoming entrance had it's own lane that joined the circle would be good... it would mean that the lane you came in on might not be the outer lane when you were ready to exit. (Does that make sense?)
Our roundabouts have double lanes but hardly anyone uses the inner lane because they want to be ready to exit.
It hadn't occurred to me that roundabouts would be less expensive to build and run, but that's probably true. In the UK there were some roundabouts that were just bumps in the road. You could just go straight through, but of course the well-behaved Brits carefully followed the circle (and so did we).
