It has secretly become unrealistic to have cars in a city, we still do it but more out of tradition. You wouldn't build parks (tho that would be nice) 1 parked car, the road next to it and the second side walk take about as much space as an apartment and we stack those one on top of the other.
Something like this is quite hilarious if you think about it.
You don't have to build it like that. Where I live now, the parking lot is effectively the basement under the apartment buildings and playground. You'd barely interact with it unless you're driving.
Housing is getting so expensive that people share tiny apartments while still able to afford two cars. With that ratio you need 10 floors of parking for 10 floors of housing.
I always thought it funny how popular elevators are for vertical travel. A monorail station in the basement or even a ski lift seems a lot less space consuming.
If it means you can get a home 120m2 (1300 sq ft) in stead of 60m2 (650 sq ft) it seems worth considering.
Something like this is quite hilarious if you think about it.

It reminds me of grazing cows having 80 times as much space as people in some parts of my country.
