It is not an overnight solution. It took many decades to get to where we are today, and it will take many more decades to reverse. Second, most American cities are really not that dense.

And that is not quite fair. I am pretty sure when we saw gas prices spike a few years ago, you could also see a dip in house prices for the far out subburbs of cities.

The article glosses over this, but the taxpayers suffer from many non-monetary costs which often are overlooked: injury risk, noise and air pollution, limited walking mobility, to name a few.
