I'm not sure I understand what the problem is. Are there really thousands of accidents at these roundabouts? I've never seen one. is traffic back up on a regular basis? I don't think I've come to a roundabout where there was more than one or two cars waiting to enter.
Sometimes I think that when people are retired and have too much time on their hands they sit around and imagine problems that don't exist.
I agree with Kitty. Let's get some hard data on the number and frequency of accidents. It would be nice to have a study done to show whether or not the roundabouts are clogging up streets and slowing down traffic.
Frankly I don't see either of these, but if you're interested go and see how these kinds of studies can be done.
