Large U.S. Cities and an Oil Crisis

Given that oil seems likely to stay above $60 for the foreseeable future, which U.S. cities are best prepared for an Oil Crisis? I'm not sure what to make of this ranking. I would love to get my hands on the raw data:

SustainLane analyzed commute trend data within major cities--how many people rode, drove, carpooled, walked, or biked to work. Then we looked at how much people rode public transit in the general metro area, and metro area road congestion. Sprawl, local food, and wireless connectivity made up our final areas of data analysis (see chart below for weighting of these criteria). The index did not take into consideration energy impacts associated with heating or electricity, which would be largely dependent on non-oil energy sources, such as coal, natural gas, and nuclear energy. Only one U.S. city in our study, Boston, uses a significant amount of heating oil. For this reason Boston, ranked #2, gets an asterisk: if heating oil usage were used as a criteria its rank would be somewhat lower.
