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.” The hypermiling movement has been criticized for its alleged promotion of driving tactics that are considered dangerous or illegal, such as overinflating tires, rolling through stop signs, and following closely behind large vehicles to cut down on wind resistance.
