Wrap your car in a golf ball for more efficiency

[JRP3]

Saw this in Pop Sci. A vinyl vehicle wrap with little indentations that's supposed to increase economy:Hybrid Vvehicles, Future Hybrid Vehicles, Drag Reducing Technology, MPG-Plus™, FastSkinz™
Are they referring to the Roadster?

FastSkinz drag reducing technology has already shown a 25% increase in fuel efficiency during "rolling field tests" on the premier BEV in existence today. This high increase in fuel economy represent a corresponding load reduction on the batteries, thus positioning FastSkinz drag reducing technology to be a strong hybridization component for future vehicles. Equally important is it's immediately availability.

Fastskinz Dimpled Golf Ball Fuel Economy - 430-mile 2009 Ford Flex vs Ford Flex Aero Test - Popular Mechanics

In view of the skepticism and past research, we decided to do our own fuel-economy testing.
...
Essentially, in our test, we found no real fuel-economy improvement from the Fastskinz MPG-Plus wrap.

Good work as always TEG, sounded too good to be true. So the sister publication to PopSci debunks the product then the next month PopSci does an article touting the benefits? Seem like sloppy journalism.
