The average price of gasoline slipped 9.2 cents to $3.509, according to the weekly survey of service stations done by the Department of Energy. But fuel prices remain too steep for consumers, who are still reeling from the effects of high unemployment. "Are the price reductions we're seeing this week going to make Americans drive more? I doubt it," said Fred Rozell, director of retail pricing for the Oil Price Information Service. "Not with stagnant personal incomes and such high unemployment, and gas prices still running much higher than they were a year ago," he added.
