But even with such dolts the roundabout is better since accidents are prone to be glancing blows instead of right angle impacts.

The best multi-lane roundabouts I've seen are at Hilton Head, they keep the right turn traffic completely isolated:

Santa -- there is a very good reason the Hilton Head circle works. Take a look at the size of it -- the circumference. The reason it works so well and that traffic doesn't back up is because of the size. I have driven many circles near large cities. They all work. And that is because someone who knew what they were doing made them the proper size.
