This dulls people's sense of empathy in a considerable and damaging way. Instead of being able to think critically and with empathy, suburbia drives people to view all of their sameness as a "good thing".
We need to break these bubbles, redraw our towns and cities with integrated services, focused on walking, biking, and as little driving internally as possible. You car for should be intra-city travel. Not for going around a fence to the grocery store that's 1000ft away.
