Fewer drivers over a barrel

He put his 2003 Toyota Tacoma truck in the garage and switched to a Honda Nighthawk motorcycle for weekday commutes to Beverly Hills. He stopped driving to the beach on weekends and cut back on trips to Hanford and Fresno to check on properties he manages. He began grouping errands into one trip each Saturday.

The trade-offs Freedner has made in the last year haven't necessarily made him happy, but they've reduced his gasoline consumption nearly 50%. And although he admits to feeling jittery traveling freeways on the Nighthawk, all the changes are permanent, unless gas returns to $2.50 a gallon.

"The price was just eating up what I earned," said Freedner, 57. "This is the best thing I can do to make ends meet."

Americans are getting serious about using less gasoline, confounding some economists who have argued that most people can't reduce their driving much because they have to get to and from work and make those necessary trips such as shopping and chauffeuring their children around.

The truth is more complicated, according to some energy experts: When the price reaches a certain threshold or the driving reaches a peak point of aggravation, people are willing to give up personal space and independence.

"There is an awful lot of what might be called discretionary driving," said Edward Leamer, an economist with the UCLA Anderson Forecast. "Raise the price high enough, and you will see that there is a lot more that people can do."

For some, the next drop in prices won't be enough to send them back to their old driving habits.

"The trend will be toward more lasting conservation and longer-term savings if they are not just reacting to prices and have instead made a decision to change," said Bruce Bullock, executive director of the Maguire Energy Institute at Southern Methodist University's Cox School of Business in Dallas.

In California, the nation's biggest fuel market, drivers have been burning through less gasoline than they had the year before for six straight quarters. From July through September, the most recent data available, Californians used 46.2 million fewer gallons, or 1.1% less than in the year-earlier period.
