Glad they filled the wake with smoke to allow a look back there.That's the money-shot!
Thank you very much!

I don't mean to hijack but the view with the smoke filling the wake made me wonder if something like Vekke built for his VW Lupo would work on my Golf. Here is a tuft test of a Vekke-spoiler, or more accurately, a Kamm-back on his Lupo.

Bob,right at the end,at 3:06-3:07 the wake is fully visualized,close-quarters to the body.
If the test section were longer,we'd see the turbulence trailing back for hundreds of feet.
As Hot Rod Magazine says,"it's the poison of speed." Also mpg!

Thanks, Phil. Clearly my eyes have much to learn.
BTW, Phil did you get my email? I'll be leaving AR soon (missed Bondo - frown) and passing through TX near Sanger en route to desert SW area for winter. If you're home I'd love to stop and shake hands.
