Record high gas prices are prompting Americans to drive less for the first time in nearly three decades, squeezing family budgets and causing major shifts in driving habits, federal data and a USA TODAY/Gallup Poll show.

As prices near — or in some places top — $4 a gallon, most Americans say they are cutting back on other household spending, seriously considering buying more fuel-efficient cars and consolidating their daily errands to save fuel.


Americans worry that steep gas costs are here to stay: eight in 10 say they doubt today's high prices are temporary, the poll finds. It's the first time such a large majority sees pricey gas as a long-term problem.

The $4 mark, compounded by a sagging economy, could be a tipping point that spurs people to make permanent lifestyle changes to reduce dependence on foreign oil and help the environment, says Steve Reich, a program director at the Center for Urban Transportation Research at the University of South Florida.

"This is a more significant shift in behavior than I've seen through other fluctuations in gasoline prices," he says. "People are starting to understand that this resource … is not something to be taken for granted or wasted."
