You're not in the suburbs. At least not the kind that cityfolk say are soulless wastes. It sounds like you live in the downtown of a village or town.
When I think of the 'burbs, I think of vast expanses of asphalt where only the poorest would consider walking and labyrinth enclaves of cul-de-sacs where taking the kid to play with a neighbor requires a half-mile drive to go 500 feet as the crow flies.
Modern design (and redesign, though that has less freedom) of low-density suburbs, while still avoiding street grids to limit residential traffic speeds, often embraces walking and bike paths that are more direct than roadways, and designs that improve transit serviceability, instead of using the branching, cul-de-sac dominated structure of, say, 1960s suburbs.
Further, I want that walk to be reasonably populated all day and into the night, so I feel safe.
Under half an hour away from work (by whatever means), somewhere I can afford to buy, quiet neighborhood, nice view, trees around, good schools, not too tightly packed, with a reputation of being safe enough that I don't have to worry if no one else is around.
Walkability is a plus, but not at the cost of other goals. If I ever want to see family or friends, a car is a given. Survival doesn't strictly require one, but it would complicate a number of things.
A big part of that is probably that I wasn't raised in a city, so my contact with them has been while on vacation. Living somewhere and vacationing somewhere are certainly very different experiences.
I live within walking distance of about a dozen restaurants and a bar. I've never been a nightlife guy. There are museums and concert halls 30-60 minutes from here. My home is fairly cheap for the area, and I live under 15 minutes away from work. I don't feel like I'm missing out.
So while I understand that a lot of people would like to live in a city, I don't see the attraction. I feel like the downsides outweigh the benefits.
