I see your point now more. I agree on roads being a band aid and pushing people further out, which if it continues requires exponential additions to roadways, which is impossible. Metro rail, on the other hand, is a different thing in allowing accessibility across the dense centre. The most effective 'acessibility' I can see is rail stations as the focal points of density.
