When drivers set out to hypermile, there is a spectrum of techniques that they can use. These range from the good - don't blast away from a red light and don't speed up then slam on the brakes at the next red - to the risky. Dale Earnhardt, Jr. may be able to use hypermiling tricks like shutting down the engine at high speeds to win a race, but that doesn't mean you should try it during your commute.
Warning: Don't try this! The safest distance to drive behind a big rig at 55 miles per hour is 150 feet. Driving any closer is insane because it puts you in the driver's blind spot and also does not give you enough time to respond if the big rig's driver changes speed.
