Seems like there is, and it's that it's very rich? Because something like this:

> an amazing park with play structures, basketball courts, tennis courts, large gracy field, a creek, picnic areas, and such about a 1 minute walk away.

doesn't exist in the entirety of my city, which also predates cars.

Also, do you mean a detached house when you say "from my house"? How many customers within 5-10 minute walking distance does (for example) hairdresser serve in such place?

Really? You have no parks in your entire city? How is that possible? I don't think that's a wealth problem, sounds more like a governance problem to me.

I live in a quadplex on a mixed-density Street. I'd guess there's a 1000 housing units within a 5-10 minutes walk. I'm sure people come from further away as well though.

You may call it well-designed, but I think that all those close amenities you are enjoying is a side-effect of high-density living for high-income people.

After all, no matter how well you design a place, that (for example) hairdresser still needs enough people who can afford the service to live within walking distance so that it can turn a profit.

I think it's less a case of "How do we design this city so that everything is no more than a 25m walk away?" and more a case of "High density population with lots of money attracts businesses to the area".

> There's nothing special about where I live except that it's development predates the automobile.

That's true for most places.

Sorry I wasn't specific enough. Predates the automobile AND (mostly) wasn't destroyed for the automobile.

Lots of America was built before cars but was subsequently destroyed for cars. Those areas aren't what I was referring to.
