Re: [OSM-talk-nl] junction= roundabaout
I do think there are situations were you want do a full roundabout. Example: want toturn left on a road, but that is prohibited. Right is allowed and there is a nearby roundabout. Then you will do a full-turn.

Re: [OSM-talk-nl] junction= roundabaout
At the other way, as we do it in Holland every roundabout should be tags in a forward and backward way in relations when the roundabout is split up. One of the reasons relation get polluted. But your drawing argument is a illegal one. We do not map for the renderers. And all relations are two sided so always the whole roundabout is used. When you draw a route from a to be the routing software has to be smart enough to colour only the part of the roundabout from way a to be into the right direction.
