The cities included in the study are Boston, Chicago, Los Angeles, New York, San Francisco/Bay Area, Seattle, and Washington, D.C. I haven't really spent huge amounts of time in a couple of these cities, but I wonder how uniformly over the cities the data factored into the decision. My impression is that NYC, Chicago, and DC have much more comprehensive public transit systems than do the others in the list (except Boston, about which I know next to nothing.) Is my impression just wrong? Public Transit just didn't seem to be nearly as big a thing in LA, SF, or Seattle in the time I spent there.
