Interesting, apart from the annoying and childish presenter!

I lived near London in the 1960's and the ringway plans looked exciting to a pre-driving age boy. But now I'm glad that, apart from the M25, the ringways were'n't built. If they had been, thousands of people would have lost their homes and by now the ringways would themselves have become congested nightmares full of tailgating White Van Men and mad lane-hopping BMW 3-series drivers.
