All I'm gonna say is if you reduce and optimize this design, you will end up with a round about.

But this one is much better if you really love u-turns

Yeah it seems like basically a hybrid of a roundabout and a Michigan left, with unclear advantages over either of those alone?

I read an article recently that said that left turns are terrible for traffic. One of the best ways to improve traffic is to ban left turns all together.

Doesn't it have an advantage over roundabouts in that the main traffic can keep moving at normal speed?
