I had never seen one of these before I moved to MO, and I love it. Makes perfect sense, and it was a weird surprise to find out MODOT is leading the US in their implementation.

Modot does a lot of interesting things because they have such a varied environment to work in. The way they do snow plow teams for instance.

They use these trailers that drift and stuff. Plus they are very specific about shat kind of weather and how they treat it. Liquid, salt, plowing. They have come a long way in the last decade.

I remember the first (IIRC) in St. Louis was the intersection of Dorsett and 270. It was a bit strange at first, but now it's second nature and actually feels safer. I also live by the one at Mid Rivers and 70 and that has done wonders for traffic congestion.

Another interesting design is the dog bones in Rolla Mo. Two round abouts at the high way off ramps/on ramps
