Aggressive driving maneuvers like speeding, rapid accelerations and hard braking, can really waste your gas. In fact, it can lower your gas mileage by as much as 33 percent at highway speeds and by 5 percent around town. Sensible driving is also safer for you and others, too, so you may save more than just gas money.
