Big Dave: I think the reason they may not is because they figure "we already get good enough mileage." Sort of like being satisfied that "a Prius has a pretty low Cd as is."

I'd love to see a Prius owner in particular do this, and then quantify the results. It would do wonders for raising the profile of aerodynamics in auto design and aeromodding as a DIY option.

Anything that opens people's eyes to the aerodynamic garbage the automakers are producing (in general) is good, in my opinion.
