Much of the new developments for residential are single family residential. A house, a garage, and a yard - on a street where you need to then go and drive to get {stuff}. Whatever you need, you need to drive there.

The older style with business on ground level and residential above that isn't as profitable for developers and so isn't made as much. Cities, in bowing to demands of developers likewise zone for single family residential and it is thus illegal to build a commercial spot (other than the strip mall along one of the busier roads - that you need to drive to).
