10 Things You Can Like About $4 Gas

Travel on all roads dropped 2.1% in the first four months of 2008, according to the Federal Highway Administration. Wherever people can take public transit, they are doing so. Even before the biggest gas-price hikes, a Congressional Budget Office study of California freeways from 2003 to 2006 showed that the number of freeway trips went down 0.7% for every 50-cent increase in gas prices — but only in areas near public transit. Cities are struggling to keep up. BART, the San Francisco Bay Area rail system, removed seats to open up more standing room.
