How would you know?

The only way to prove or disprove the statement is with a wind tunnel.

Wind streams and their effect on a vehicle is not what it would seem to be. Ever seen a tractor trailer with those silly extensions at the end of the trailer? They have a significant effect on fuel economyOne would think the front area effects most wind drag but a wind tunnel proves it the end not the front!!!!!!!!!!!!!!!
