This is a fascinating article, thanks for posting.<p>It&#x27;s unfortunate that so many U.S. cities (and some abroad) were designed and built in a way that results in them being unwalkable. I&#x27;m really interested in seeing how cities respond to this, and whether or not these cities will start to become more dense in order to possibly improve efficiency, or whether they&#x27;ll just continue to sprawl because it&#x27;s the easiest way to grow.
