Oxford University Press US word of the year: "hypermiling"

Oxford Word of the Year 2008: Hypermiling. Do you keep the tires on your car properly inflated to maximize your gas mileage? Have you removed the roof rack from your vehicle to streamline the car and reduce drag? Do you turn your engine off rather than idle at long stoplights? If you said yes to any of these questions you just might be a “hypermiler.”
