Myth #5: Improve mileage by drafting behind 18-wheelers.
Yes, this technique worked for bicycle racers in the movie, “Breaking Away.” For a car, the positive effect on mileage is negligible while the risks are potentially fatal. If an abrupt stop occurs, the trucker cannot see your vehicle behind the rig. If you are unprepared, the truck can out-brake you. This would cause you to crash the truck’s tailgate and your windshield. Are you searching for the quickest route to a cracked windshield? In that case, give this myth some credence.
