It may not be as simple as changing orientation of the polygon or relation, 
because many roundabouts aren't but a set of segments joined by the ends.

Additionally I have noticed some of them to need some improvements apart
from the orientation: accesses to roundabouts needing be splitted,
roundabouts that should be round and aren't, etc. This roundabout
orientation issue can be a good excuse for some local improvements around
them, which isn't a bad thing.

Cheers.
