" In everyone's wanderings around and musings on aerodynamics, are there any good aerodynamics cheat sheets?"
Just look up the posts here on this site by Aerohead ( " Aerohead aerodynamic seminars " )

As far as the shape of the front of the truck. I took it to mean that the blunt shape was
as efficient as the sloped front end - not better than.
As far as the 'scoops' on the sides of the bumpers on cars, some do indeed act as 'air curtains'. In fact, it was even mentioned in the video of the truck about the 'air curtain' effect on the truck (at 2:10 in the video ). What i found interesting though is that they seem to be using the gap in between the bumper and the front end to channel the air around the wheels, versus sealing this gap.
