That is part of urban planning here. Public transit simply can't be both good and cheap at these densities, which were mandated explicitly by urban planners. You complain about height limits, but there are many places which you can't (or recently couldn't have) house more than one family in a certain amount of space by law.

There are lots of post-car places where you can get around great on foot, it's just that a lot of the post-car places in the U.S. and Canada have many layers of planning and regulation which make you dependent on a car.
