I can think of a lot of places where you could add these to the trailing edge of something on a car to improve drag CF.
- You could add a lip to the trailing edge of a hatch-back and it may work like/better then our standard VGs.
- You could add it to the trailing endge of the lips of the front bumper that some cars have
- You could add it to the trailing edge of side view mirrors
You might be able to put them in any of the places you might put normal VGs and it may have the same effect...
