So who wants to live in the civilization in the top picture?
I don't care if I am called a hippie! I don't want to breathe toxic chemicals!
I would say that we use the mass transport to get resources back and forth to build local cities as sustainable campuses that are SELF sufficient where people can use bicycles and other means of traveling within their complexes, and cut down on the mass traffic jams of cars and trucks.
Shuttles can be used to get people around city-states organized like satellite campuses.
And then organized transportation can connect these cities to each other or in a hub.
The main thing we need to get rid of is crime and corruption that prevents people from coordinating resource more effectively. As we solve those problems, we'll see more sustainable planning and development in our communities first, then statewide, nationally and internationally.
