Default Aerodynamics acording to Myth Busters!


"Denny" wrote in message ups.com...

Paper material in the bed of my truck at 55mph rotates once or trwice
in that standing vortex then vanishes over the tailgate - never to be
seen again...
Any empty, plastic gas can left against the tailgate slides up against
the back of the cab - again that standing vortex...
Now, that the gate up has less drag overal still amazes me, in spite
of knowing what is theoretically happening...

I forget which brand truck we were looking at (Ford?), but it had a sculpted shape to the top of the tailgate about 8"
wide. The salesman said it helped to improve gas mileage...
