Better is drawing a diamond shape in Potlatch, then pressing 't' to tidy  
it. Presto! A nice tidy circle! Put the diamond points on the roundabout  
itself and the circle will overlay the road correctly. More complex  
roundabouts with dual carriageways entering are no problem, either.

My opinion, in this seemingly endless debate, is that those roundabouts  
that are merely painted circles are mini_roundabouts, regardless of if  
they exist in Australian Road standards or not. However, once you add an  
island and kerbing, they become a full roundabout, and need (IMHO) to be  
fully drawn and tagged appropriately. That's how I've been doing them
