When a hybrid isn't enough - hypermilers go to the extreme

Bob Winger is that guy on the highway, puttering along in the far right lane. As Chevrolet Tahoes, Cadillac Escalades and a host of other cars and trucks whip by in the passing lanes, Winger slowly accelerates up to the 60-mph speed limit on Interstate 64 in Newport News. He eases up on the gas a bit, fixated on a display next to his speedometer that shows his mileage. For short stretches, his 2006 Honda Civic Hybrid gets as much as 90 to 100 miles per gallon.
