[DeTomaso] Airflow testing

[Will Kooiman]

GREAT test.

I'd also suggest some longer tufts - or even some short, some long.

Thanks for doing this test.  I'll help support the test by contributing $
for the yarn.  Tell me where to send my $1.

Looking at the video, my interpretation is mostly in.  If you look at 
how the tufts sit in the first frame.  They are sticking out while the 
car is sitting still.  Even at 60 mph at the end of the video the tufts 
are alternating between flat against the grill and partly sticking out.

Though I believe that the conclusion that more testing is needed, is true.
