What if, every sprawling non-walkable city/suburb block took all of the houses on that block and made each one a floor of a single building, with balconies, patios.. And the remainder of the land was all green space. Scaling up a walkable city does not appear to work, how about improving the sprawl to be more self sufficient, green etc.
Decades of Sim city and we havent learned anything?
Random thought.
