Well, the elementary school is two blocks away, the middle school is two blocks the other way, and there is a high school about four blocks away (though by high school the neighborhood school isn't as relevant, at least in NYC). There are little league soccer and baseball teams that practice & play games at the small park a block and a half away and the larger park three blocks away. I'm pretty sure that neither of those particular developments require a car.
We do frequently use a car (when leaving the city, for instance), but we don't have any reason to own a car. And more critically, we aren't chained to it in the way that so many friends and family are, by virtue of every necessity lying well beyond walking distance tucked inside a giant parking lot.
