I've been using this roundabout twice a day for the last 20 years and can count the number of accidents I've seen on the fingers of one hand.
Now, you only need 2 container trucks following each other and they take up the entire distance between the sets of lights causing the traffic to back up on the roundabout and the resultant congestion. It's a similar situation to the Charlotte Place roundabout which used to work perfectly well until they installed the traffic lights.
If it ain't broke, don't fix it.
