<p>Maybe we should have roundabouts as a relation, containing all the road segments which should produce a closed polygon. Then we put the centre obstacle stuff on the relation. That would be closer to the OSM model of having one OSM object for one real-world object. Then a magic roundabout could be modelled as a nested object with the individual roundabouts as members.</p>
