Seems to me that the article does not get the reason why people move to big cities: > So what do we achieve by building new highways and speeding up travel? We don't actually shorten people's trips; we just enable them to live and work farther away from each other. If people can live and work farther away while keeping travel time the same, then they have more opportunities for work and leisure in their reachable distance. That is major advantage of living in a big city compared to a small town.
