Have you seen the size of the big trucks Ed? The present roundabouts in total are almost too small for some of them. The walls would never work and I think would cause accidents. I said it was a good thought, but just, in my humble opinion, not workable. Why don't you submit your idea to the DOT and maybe if I'm wrong and your idea is revolutionary it can be as common as the "Jersey" guard rail.
