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.
We thought we'd found the filthiest car when we gave away a vacuum last spring, but apparently, Ann Biglan of Massachusetts wasn't going to be passed over again this year.

Perhaps the car was struck by lightning and the decaying organic matter came alive, Johnny Five style. While cruising along in Yarmouth, Massachusetts -- on fairly provincial Cape Cod -- the detritus rebelled.
