There are 10,000+ roundabouts in the US and the number is growing rapidly. One could argue they may even be overused in certain areas (exhibit: Carmel, Indiana).

There are more than 15k only in Spain. 10k in the US is nothing.

So about 0.003 roundabouts per square mile, or 1 roundabouts in 380 square miles

What's the significance of roundabouts per square mile? It seems pretty meaningless if I'm honest. There's huge swaths of rural land where roundabouts are totally unnecessary.
