I dug around autospeed a little more, and found some more information http://www.autospeed.com/cms/A_3061/article.html. They specifically tested the air tab product and they did have promising results - similar, in effect to my tuft testing while behind a semi.

There are four articles there...good reading. But with their last test on the Honda Insight...why weren't the airtabs placed up above the rear glass as with the Toyota Prius right above? Separation not expected? Not a fair test...who would expect improvements on an aero tweaked shape?

They need to test something like the green Honda SUV.
