Wouldn't it be nice if each town were distinct and surrounded by a green belt of permaculture? I think the distinction would help residents of each town have more pride in their individual city.
I aligned the freeways the way I wish Robert Moses would have, so they go around each town instead of cutting through and dividing cities in half. If this were the case, I think people would be less likely to use the freeways for anything other than regional commuting, like the autobahn in Germany. Therefore, it wouldn't have the congestion that our freeway system has today.
Also, think if each town were connected by a light-rail system, and then each individual town had a smaller scale street car system and bicycle trails, it would be amazing!
If only.....
