[Tagging] Dispute on highway=mini_roundabout

[Nathan Edgars II]

I just went through the mini_roundabouts in east central Florida. I 
found one definitely mountable (in an industrial park), 202 definitely 
not mountable (including some culs-de-sac), 3 that I'm not sure about, 
and 4 mistagged turning_circles. Obviously this says a lot about 
roundabout construction practice here, but also shows that many 
non-mountable roundabouts are being mapped as nodes with 
highway=mini_roundabout. 105 of those 203 were last edited by me, with 8 
other mappers in there, mostly known locals.
