Thank you John for clarifying that. Here in UK roundabouts are large and well-signed, with reflective arrow-boards, so you can't miss them in the dark. They usually have 2 lanes and there is a correct procedure for entering and leaving them. When I was prison visiting, I often drove to Hemel Hempstead in Hertfordshire, where there was a notorious Magic Roundabout. I'm a safe and confident driver, but every blooming time I headed for this roundabout, I ended up somehow going the WRONG WAY around it, becoming a trembling wreck. People later told me everyone did this, but the Herts Council seemed not to worry. I expect it's been sorted out now.
