Pturner, I so agree with you. Roundabouts are so simple that they should be used everywhere. They look better, move traffic better, cause less accidents and are easy to use.
Think of a roundabout as two four lane roads meeting with a traffic light. If you were making a right turn, you would always approach and enter from the right lane. If you were making a left turn, you would always approach and enter from the left lane. And if you were going straight through, you would use either lane and stay in that lane all the way through the light. Roundabouts work exactly the same way.
There are only four rules to make roundabouts work.
1. Cars already in the roundabout ALWAYS have the right of way regardless of which lane they are in.
2. If you are turning right, 90 degrees, approach in the right lane and exit from the right lane.
3. If you are going straight through, 180 degrees. enter from either lane, stay in that lane and exit from that lane.
4. If you are turning left, 270 degrees, enter only from the left lane and stay in the inner lane and exit from that lane.
