Expensive Gas Equals Less Driving

"The drop in driving was small - the average American drove 13,657 miles (21,978.8 km) per year in 2005, down from 13,711 miles in 2004 - but it is more evidence that the market works and prices help control consumption, Boston-based Cambridge Energy Research Associates said."

"Growth in U.S. demand for gasoline slowed from an average 1.6 percent per year between 1990 and 2004 to 0.3 percent in 2005 and 1 percent in 2006, the report said."
