What happens with Roundabouts in place -part two

[HunterstonB]

The first modern roundabout's were introduced in 1966 in the UK and had replaced about 90% of intersections by 1980. They rapidly spread to the rest of the world. The USA is the last major country in the world to introduce them.

This is amusing because its as if this 'new technology' The British have had over 50 years experience with them!!!

To Europeans its a little like listening to someone explaining how telephone works. . . . .
