Outside of large trucks on dirt roads or aircraft landing photos, I do not recall seeing vortex formation on automobiles.

Have seen a few tufts flicking about in videos.
While it would be nice to be able to see the vortices, you can directly measure their drag and lift outcomes by simply measuring panel pressures. After all, all drag and lift forces just come from air pressures acting on panels.
