Car centric cities. Cities can and should be designed for people, keeping cars mostly out. The result is beautiful cities designed for people that make governments lots of money but the car companies will be earning a little less, ooffff
Make cities walkable, create actual safe roads for bikes, create 15 minute cities.
Lol no it's not. Been there once, and it's an ugly shithole. Compare Montreal to any people first city and you can either agree it's shit or lie. Give me trees, give me places I can walk, give me nice clean fresh air, give me silence, give me cities designed for humans.
The problem is, our cities (most of them) are already designed for cars. To change them to accommodate walking and public transit would be somewhere near the largest sociological project the world has ever seen. It would require upending every single aspect of everyone's lives in order to refit them around walking and public transit. I think it's unreasonably infeasible at the current time.
