There always exist those determined to push the very limits of their cars to the max. But here's a Mother Jones article about a new breed of competitors: "the hypermilers".
We glide for over a mile with the engine off, past a gas station, right at a green light, through another green light—Wayne is always timing his speed to land green lights—and around a mall, using momentum in a way that would have made Isaac Newton proud. "Are we going to attempt that at home?" Cathy asks Terry, a talkative man who has been stone silent since Wayne executed the death turn in his car. "Not in this lifetime," he shoots back.
Wayne is paying attention to the road, not the banter. He's had to turn the engine back on earlier than he usually does after taking the death turn. "I hit the turn at 50, 51," he says. "I should have hit it at 52."
Sheesh! Could just buy a bike you know.
