So we need to do one of the following:
1) "Force" everyone to draw a loop around the island (too tedious)
2) Change definition of mini_roundabout to allow for non-traversable
islands (not happening, since it seems a traversable island is nearly
universal, even in the US [1])
3) Invent new tag
4) Tag as turning_circle, perhaps additionally using a
traffic_calming=* value such as island [2]

My vote is for #4. Time for me to try out Overpass to get my
mis-tagged features...
