Good to see they finally point the finger at what is fairly certainly the culprit: the automobile.<p>When i lived in NYC, i knew most of my neighbors. Why? because we literally bumped into each other coming in and out of the building. When you have a common destination (subway, bus, market, etc), it's nice to have someone to chat with, but when your commute is in an automobile, you never get a chance to ask. Living room, garage, automobile, parking lot, destination.<p>With automobiles, there is no opportunity to, say, bump into your neighbor and ask, and then follow up with quickly knocking on your neighbor's door to see if they are still interested in joining you. Without those quick opportunities, relationships cannot form. Without relationships forming, it's culturally awkward to ask directly.<p>The single occupancy automobile, and the decentralized suburbia that formed around it are very probably central to many of the ills detailed in the article.
