Yes, it worked for bicycle racers in that movie, "Breaking Away."

But for a car, the effect is negligible while the risks are potentially fatal.

"In fact, it's a really bad idea because if the trucker has to stop, you can't see what's in front of them and they can't see you," says Duchene. "If you're not paying attention, they can outbrake you and you're going to drive right underneath the tail and the tailgate is going to hit you right in the windshield. Thank you and good night.

"Not to mention, if you don't already have a cracked windshield, that's an excellent way to get one."
