New York, San Francisco, Boston, Chicago, and Philadelphia are towns with the best walk-score in America.

For various reasons, it is still much cheaper to live in the suburbs and commute into the city than to live in San Francisco. I wonder how the other walkable cities are fairing.

Perhaps when people buy homes, they tend to not buy a new car at the same time - prior to the housing crisis, many people bought lots of homes. Then the market collapsed and they lost their money, further reducing the number of new cars bought.

Oddly enough, some 2000-model-year used Hondas and Toyotas did not depreciate in value between 2010 and 2013 because the used car market heated up.
