> Many people who live in urban areas neither own a car nor want to drive.
By "many", I understand you mean "few". I live in Seattle, which has one of the better transit networks in the country, certainly better than average. Yet, 85% of households own cars. In the suburbs, that percentage is even higher.
> Also, suburbs are boring as hell. There's literally nothing to do outside except stare at parked cars and locked houses.
That hasn't been my experience. There's lots of things to do in suburbs, you just need to drive there. The rest of your comment is about some difficulties of doing walks in suburbs, which are quite foreign to me -- for one thing, I'm quite sure that almost everywhere in Seattle metro area, you're not more than 1 hour walk from a convenience store. Given how millions of people love going hiking in places even further from convenience stores, gas stations and water fountains, I don't see this as such a huge problem. The rest of your complaints are simply matter of your preferences: I for one thing couldn't care less about presence of places to walk into and explore. I'm not a tourist in my own town, I need to get places and get things done, and idly walking around the business districts is not one of my hobbies.
