Cities exist to serve people's needs. The 2 existing models are a relic of a low technology past: suburbia with long car commutes to downtown, and dense cities built around facilitating mass daily movement to the office through subway/public transportation. Instead, we need self-sufficient neighborhoods catering to different lifestyles and needs (some higher density and walkable, others still car-centric but encouraging shorter car rides) with limited need for long car rides or large investments in mass public transportation.
