I agree, but have yet to see vortex formation in any of the wind tunnel and smoke images posted.
Is the smoke just too weak and dispersed by the time it gets to the end?
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.
