There has been a pretty lenghty discussion in the German forum just a
couple days back which i started. 

I started a discussion about mini_roundabouts here too a couple years
back.

I still find the concept of tagging a "mini roundabout" _broken by
design_.

The main difference we have in usage is - A mini roundabout will never
cause any announcements like "3rd exit" it will be "turn left". This
will be pretty confusing for anything larger that a small residential
street. 

And i think the misconception is still what a mini roundabout is. 
A mini roundabout is not a mini roundabout because its center is
traverseable. Its a matter of fixing a priority problem in busy
junctions. 

So in case you have 12m diameter and a traversable center i would not
say thats a mini_roundabout.

And while at it - We should introduce a tag "traversable=yes" or
something on the junction=roundabout way.

  Any sufficiently advanced technology is indistinguishable from magic.
