How to ease the pain at the pump - BusinessWeek Online

Validation!! From the article: "Want to really improve your fuel efficiency? The biggest fuel-burning culprit is frequent accelerations and stops. You see everyone doing it, racing to the next stop sign and slamming on the brakes. It may get you to work faster, but what's the cost? Reed found that people who make quick starts and stops burn up to 37 percent more fuel than those who coast between lights.
A variation on that strategy involves using your cruise control. People on the highway tend to react too much to what their neighbors are doing, racing ahead to eliminate the gaps between cars and braking when the pack slows down. Better to use the cruise, tapping it up or down whenever you need to adjust your speed. Watch your speed too. It can have a significant effect on fuel consumption."
Last line: "It seems a lot more people should be using the cruise control." :)
