for density in cities to increase, more public transport is simply needed. Cars are a terrible way to get around in a crowded city. The city is far too dense to drive easily, cars take up way too much precious space and are huge increasers of smog. In germany and other european cities, they already started banning diesel and other high pollution vechiles from entering major city centers because of both smog and congestion issues. This kind of ruling will only increase.
