VGs actually do something.
But wether they reduce FC is another matter altogether .

I've tested glider VGs (dimple tape) on Hägar, and was rewarded with less noise around the A-pillar.
With the tape gone now, I have more noise.
Though it's become hard to hear with a grinding wheel bearing.


I've seen bugger all effect of the dimple tape on the rear end of the vehicle - the dimples are simply too small to effect the disturbed airflow back there.


But Susanne says their pods aren't VGs ...
