That's incredibly expensive to build.

It's not. And it is a common practice (or even required) in lots of cities with tight space (e.g. Barcelona).
Yeah, cities that are not in the active earthquake zone lovingly called The Ring of Fire. Remember, the approach to the Golden Gate Bridge cost 1 million per foot of road up to it.
Puzzle parking systems[1] can make it quite affordable.

How? You know have a 4 story building that you can sell?
The ROI on the buildings wouldn't justify it?
