That's right the Rule is you must always give way to vehicles already in the roundabout.

We all know its like a first in best dressed in real life.

If the red car was in the round about before the green car it has the right of way, it can move from the inside to the outside lane to leave the roundabout and the green car has to give way for it to do so.

Our biggest problem is people cant merge smoothly, they seem to be unable to grasp the concept of meeting the flow and to slot in, people push in or drive to slow to merge, this at a 2 lane roundabout is a recipe for disaster and causes most problems, if they can grasp the concept of merging and which lane they need to be in, it flows quite nicely 90% of the time.
