"It’s pretty easy to destroy a walkable place. We’ve been doing it for so long, it’s almost second nature. First, prioritize auto travel. Require every new building to be surrounded by lots of parking; and require every new street to be designed for high-volume, fast-moving traffic. Second, designate separate areas for people to live, work and shop, and don’t allow any of these “uses” to mingle. Third…. Well, actually, the first two will do it."
