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.

I believe that some of the YouTube videos shot at A2 allow for vortex visualization.
Driving down leaf-strewn roads in the Fall are a great opportunity to observe vorticity.
Air Tab inventor Wheeler photographed long, vortical yarn streamers coming off the sides of the roof of his Honda Accord if I remember correctly, in a Popular Science article in my photo albums somewhere.
Modern curved-roof designs have really mitigated this phenomena.We've come a long way since the mid-70s. And then there's the Porsche Cayman.
