Why Saudi Arabia Is Building a Linear City

5:55 He stole my idea!!! I wrote a story, as a kid, with this setup for cities to be like this. I modeled it after how some spaceships, I also envisioned, should look like. The surface is meant for trees and agriculture and no vehicles, except the necessary transport; the level below that would work like the shipping lanes and would also be where the roads and the hub of many transportation would connect.
I was inspired by how malls are setup, as kid I was into architecture, and engineering. Many shopping malls have spaces primarily for just people to walk around, some are even setup to look like a town allowing only access for bikes and small crafts instead of larger vehicles. In some malls, there are corridors and halls reserve only for the staff and stock to go through which also allow for some jacks for hauling products where none of the customers can see.
