I live in Australia, but I've also driven in the UK and parts of Europe. Any roundabout I've used has worked in the same way -- as you approach the roundabout, you must give way to vehicles already on the roundabout. Relevant to the circular road with T-intersection analogy, I'm reading the Wikipedia page[0] on T-intersections and I must admit the concept that "vehicles on the right always have the right-of-way" makes absolutely no sense whatsoever. But I suppose that weird rule would screw up the circular road metaphor.
