More than four years ago, Clark published a poll asking people what price gas would have to reach for them to change their driving habits. The No. 1 answer was $2. About 44 percent said gas would have to reach $2 before they would drive less. Well, that was in February of 2003, when gas was $1.35 a gallon. Today the average price in the country is more than $3 a gallon. And, in a recent ABC poll, people said they would be compelled to change what they drive or how much they drive once gas hits about $4.40. In the west, the price was $5.12 cents. It just goes to show that people adapt to change just fine, even though they may put up a bit of a fuss.
