They are also spreading in the USA. New Jersey has had them for quite a long time, and is building more. I've been surprised to see them as an apparent new default for new intersections in central Wisconsin where my wife's family is from. There are even some new ones being added around Santa Fe where I live.

Yes, I agree both that they are objectively superior and that happily they are spreading!

At first I would see people treat them like a slight curve in the road and blow through them, but we seem to have figured them out now

The ones in Indianapolis suck because heavy traffic flows can blow through as a train, completely blocking entry from other directions.

Any SF-based Adobe employee will attest to the novelty of working next to The City’s only rotary.
