Double siphon? I can see it working but only under optimum conditions.

I'm following some car down the road yesterday on the highway and he/she has a couple of chunks of snow on their rear window and trunk section about the size of 4-loaves of bread.

Mind you, no other cars or trucks have snow on their cars at this time, so it really stood out.

All I kept thinking was the amount of time and money to make this particular car aerodynamic, and they could not bother to knock it off.

The air-curtain posted would not fare well in current conditions I'm afraid, but I'm cheering the designers of them on.

Yo Dawg, or Sup Dawg, is an image macro series based on portrait shots of American hip hop artist Alvin Nathaniel Joiner,[10] better known by his stage name Xzibit, and humorous captions that are composed around the recursive phrasal template "Yo Dawg, I herd you like (noun X), so I put an (noun X) in your (noun Y) so you can (verb Z) while you (verb Z)." Since rising to popularity in early 2007, the series has been considered one of the most well-known and longest lasting examples of recursive humor on the Internet.

Do you think Audi stole this from Hyundai?
Lately, Hyundai has developed an obsession with Air Courtains. But it was not the first manufacturer to apply this solution. What I find notable about Hyundai, is the deflector mounted on the rear exhaust.

No, you misunderstand--freebeard "stole" the meme "we put air curtains in your air curtains so you can air curtain while you air curtain" from my post a few months ago. The phrase "good artists borrow, great artists steal" comes from T.S. Eliot who was talking about poetry specifically ("immature poets imitate, mature poets steal"), but it has since been jokingly applied to artwork in a variety of media.

As far as I know, the first manufacturer to use air curtains was BMW back in 2012, then Ford in 2015 on the Mustang and F-150. Now, just about everyone uses them, but Hyundai and Audi are the only two companies of which I'm aware which use double ducts like this.

I did not know that. I will accept the premise if you provide a link. I reject the conclusion though.

I'm guessing, they're below 20-mph airspeed to prevent dilution of the smoke, while compromising the fixed-Cd, creating the erratic image in the process.
Running at 20-mph, or faster would have provided the 'steady' smoke filaments ( like VW has used for their XL1 ), but that'd require a long-exposure, still-photograph in order to 'show' them.
Imaging the baby template car at DARKO was similarly challenging. White on white ,low contrast smoke flow, at supercritical Reynolds number.
Centerline-only illumination, in an otherwise, darkened test section, or something like the A2 Wind Tunnel's darker test section surfaces would have provided more visual contrast.
