Becoming increasingly common here as well. Never been unusual though.
I found this part of the article amusing:
But beyond Carmel, there has been greater resistance to them. One newspaper columnist in Atlanta says this undesirable European import will lead to higher taxes and accidents.
As they´re much less maintenance intense, cheaper to build and nearly always cause less accidents than intersections.

We used to have them.
They used to be all over New Jersey, for example.
So Twentieth Century!
The increasing traffic made them obsolete,
so we got rid of them.
Now we have intersections controlled by traffic lights,
and the occasional overpass.
Overpass i can understand, but compared to intersections with traffic lights? Roundabouts are WAY more efficient.
