Hyper-Miling?

I’ve always been kind of a slo-poke while driving and right now I should be sporting a bumpersticker: “ ’SCUSE ME, I’M DRIVING FOR MILEAGE” Lately I'm shifting to neutral on some of my commute stretches where it makes sense. A truck with a boat-rack needs to sip sometimes. Haven't had the guide-boat in the water yet this summer. Have you read about trucking companies adding/adjusting governors to limit the tractor’s speed to 62 mph? It’s not supposed to make a trucker’s run much longer but really save fuel . Commuters who say they’re always running late can’t see themselves slowing-down I guess. On my usual run to and from, it’s people and other vehicles, including bicycles that keep my governor engaged and my head on a swivel.
