I first posted this in the Unicorn Corral because I thought that was were debatable topics were supposed to go. Turns out I was wrong about that somehow, so to gain a wider audience and hopefully discover with other's help the proof that these work as patented, I now re-post it here.
Vortex strake device and method for reducing the aerodynamic drag of ground vehicles Patent Number US7255387 B2
Patent US7255387 - Vortex strake device and method for reducing the aerodynamic drag of ground ... - Google Patents
If I were to think of this as a rain diverter on a roof, such as found over an entry-way I'd say yes, it works.
However we are talking air pressures and vortexes which have a life far from and beyond the moving body.
What say yee?
I found this quote in the forum.

Fences and strakes are used on aircraft, so there might be something to this patent in my opinion.
We also see similar (
but not exactly the same) features on more and more racing cars, and they are being regulated by the rules because they work, right?
Question:
1. What tests have these devices passed?
2. Where are they being used?
I await your research, and I'll do a little as well when I can get to it.
