"Hypermiling” or “to hypermile” is to attempt to maximize gas mileage by making fuel-conserving adjustments to one’s car and one’s driving techniques. Rather than aiming for good mileage or even great mileage, hypermilers seek to push their gas tanks to the limit and achieve hypermileage, exceeding EPA ratings for miles per gallon.
Many of the methods followed by hypermilers are basic common sense—drive the speed limit, avoid hills and stop-and-go traffic, maintain proper tire pressure, don’t let your car idle, get rid of excess cargo—but others practiced by some devotees may seem slightly eccentric:
• driving without shoes (to increase the foot’s sensitivity on the pedals)
• parking so that you don’t have to back up to exit the space
• “ridge-riding” or driving with your tires lined up with the white line at the edge of the road to avoid driving through water-filled ruts in the road when it’s raining
