But, still... I get what your saying, but would not the individual molecules simply be less likely to take a path at 10:30 or 1:30.
Yeah, half bodies, I didn't type 6 when I first typed a response.

Sure, the air molecules would LIKE to take the easy path. But the air molecule before you already did. Easy path isn't so easy. Air molecules bumping into one another. Energy wasted.



Another thought. A .21 Cd for the shape on the right makes things like the Dryden van (which is shaped like the right shape) seem pretty good at a .25 Cd (approx. - from memory) in the real world. Hmmm....
