You're exactly right! Generally, if I'm going straight through, I prefer to be in the right lane. The reason is to avoid the, too often, situation of drivers in the right lane illegally going 3/4 around the roundabout (essentially making a left) and cutting me off, or worse. Of course, staying in the right lane subjects one to the left lane drivers who immediately change into the right lane as soon as they go through the roundabout, without accounting for the cars already in the right lane.
