If you did it once or twice three years ago, but haven't since, it's to be expected.
Uh, wow. Never saw one of those. Of course, in my neck of the woods, I've only had the experience of about three roundabouts, and one of them was a suburban mini-roundabout with an island not more than 15 ft. in diameter. (If that; I'm no good when it comes to estimating sizes.)My pet hate is traffic lights on roundabouts, worst of both worlds... one or the other please town planners.
