But if you are curious, then experiment. Share your tuft testing here.

I don't plan on spending anything to make the VG array... I can get scraps of coroplast(trapezoid shape 19x15) for free at work, I plan on using that to make the VGs... All I need are nine 1"x2" right triangles and a 1" wide strip the width of the roof, and tape to hold it on...
I do need to figure out how to photograph my tuft tests, as I usually take photos with my iPad, and I'm not about to hang that outside the car for photography...
Anyway, the roof is one of the last places I'm gonna look for a gain, because that is harder to decide on a path... I need some sheets of coroplast to make a belly pan and to make wheel skirts, and maybe buy some cheap hubcaps to smooth out...
