Here's an anecdote. My little brother has after school band practice 30 mins drive away. What does he do after school? He can't walk home, so he has to wait for me to pick him up. He can't go out to a movie with his friends because it would involved several parents taking the time out of work to send his friends there, and pick them up. He can't walk home or ride the subway because it's a freaking sprawl of highways. Bus stations are few and far between, and hugely unreliable. Instead all he knows is the highway that connects the school to home, and relies on my driving instead of his own two legs to get him home. I wonder why Americans are obese, hmm.
I watch animes that depict life in Tokyo. There is never a car involved. Kids just walk home after school, walking to a restaurant with their friends if they feel like it, hitting up a local 7-11. They can explore the local park, go to the movie theater, walk home with their friends if its on the same way.
I've stayed in Paris for 2 weeks and could literally walk everywhere. It's amazing how good it feels to see a cool gelato shop in yelp, proceed to take the subway with a bunch of strangers, walk a bit to the gelato shop, buy my gelato, and sit in a nearby coffee shop eating it. And want to check out some comic books? There's a comic book shop around a mile away, let's walk there.
People were not meant to live in suburbia. We are a social creature, we need to belong in a tribe, not a single home separate from the world.
