Another very interesting article...thanks MetroMPG!

Not that it makes much difference to the author's points...but he uses the term "laminar" when he simply means "attached". There is very little laminar flow on any car, because any irregularity bigger than a couple of hundredths of an inch will trip the flow. The flow may still be attached, but it is now turbulent. Any body parting line (hood, ornaments, bug splatters, paint chips, trim, doors, etc.) will trip the flow. And there isn't a lot of drag difference between laminar and mildly turbulent flow, either, so long as the flow remains attached.

Other than that relatively minor point, good article!
