If roundabouts are so good, why are the Brits installing lights on them?
I know the M6 as I too go to Wolverhampton to visit family. To get back on the M6 to go south, I go through five small and two big roundabouts. Both of the big ones now have lights.
They are installing lights on most of the big ones in heavy-traffic areas. They are installing four-way stops, too, on some of the smaller ones that were six-foot ones before.
The people are having fun with them, learning how to use them. Roundabouts work if the traffic isn’t too heavy.
