In fact they are just that in many places.

I've never seen a convincing theoretical explanation of why increased capacity must fail to solve the problem of regular traffic jams in every case, but I have felt the claim made in the OP ("the car infrastructure increase just guarantees more congestion... no matter what happens") to be true based on my own experiences. Or to put it another way, in my (admittedly limited) experience, I've never seen or even heard of a large community in the US or Canada in which motorists don't suffer from congestion on a regular basis, no matter how many highways have been built. Are there any?
