Seriously, americans need to learn about these.
> In 2000, the U.S. only had 356 roundabouts. Over the past two decades, that number has grown to over 10,000.
It's great news all over that the number is clearly increasing, but still a very long long way to go until it becomes widespread.
So 59 000 roundabouts for half the population versus 10 000 in the US.
That's a deficit of 90% per capita :-)
For my other Americans, read the Australian's post above. Can get across an entire town without stopping as a reason to remake our towns with roundabouts.
The us does not have loads of them they are few and far between
The De Soto Plaza in in Coral Gables, FL, built in 1925, as seen at https://www.google.com/maps/@25.7450124,-80.275242,3a,75y,75... is not a modern roundabout. Granada Blvd does not indicate a yield-to-enter, while the others streets have stop signs.
I think that one should also have splitter islands.

I think Cocoplum Circle might count as a roundabout? https://www.google.com/maps/@25.7059315,-80.2608362,3a,75y,1...
There are also "traffic calming circles", which are not roundabouts. "Traffic calming circles should not be confused with roundabouts, which are designed to handle much higher traffic volumes and reduce vehicle delay." - https://www.sfbetterstreets.org/find-project-types/pedestria...
