Remember those times when people said, "Don't worry, something like this would never happen, and if it did, people wouldn't let it happen." Turns out you're wrong, dipshits.
Eliminate cars.
Eliminate the options for people to be autonomous.
Pack everyone into major metropolitan cities by the millions.
Stop building houses.
Build Up.
Build condos and apartments.
Eliminate the option for people to buy land because it is unsustainable and the state knows better.
Sounds like a perfect dystopian society.
