Indeed, the aircraft is not yet flying. That's why I stated earlier the vortices are not very strong on the take off roll compared to when the plane actually takes off. See the video below; the Cub has already landed, the AoA is minimal, speed is low. But still we see the wingtips creating vortices. I can imagine a large jet building up speed during the ground roll would produce some amount of vortices as well.

Again, I trust the folks at Asobo have done their research and tried their best to implement jetblast and wake turbulence correctly.

 

Take note. When do the vortices stop? Then when the airplane is rolling down the runway and the mist is being blown, do you see wake vortices behind the airplane?

Good video testing C172 power-off and power-on stalls in the tech alpha plus some other aspects of mountain flying

Do you know if Jeff Favignano is a real life C172 pilot? It appears from his comments and what he said in the video, he is a real life pilot. I'm just curious as to whether he also flies the Cessna 172 in real life.

Wrong. V1 doesn’t determine lift. V1 can wildly change based off runway length and condition. It’s a speed that determines whether or not it’s safe to reject a takeoff. Not whether the airplane can fly. 
 

Agreed. And you are saying at V1 or below there is no turbulence at all? I doubt that. They are building during the take off roll and get substantially stronger when AoA and lift increase, in other words, when the plane lifts off.

That video is inconclusive at best.

one can see the wake form in the fog when the plane is still above the ground. Meaning it’s flying. Then when the airplane is one the ground, those wakes that were already produced are behind the airplane doing there thing in the fog. You can see when the airplane touches down. There are no more wakes being formed. It’s clear the airplane is past the fog when on the landing roll.
 

 

But look at the speed and the AoA of that Cub. Still vortices are being generated; I'm convinced if the mist area was larger we still might see them being generated during the roll out.

Well, they stop because the spoilers are immediately deployed, which basically destroys lift and thus the vortices.

Let's agree to disagree here and find out how Asobo has given shape to turbulence and jet blast when MSFS2024 is released.

Agree to disagree for sure. This is the part where I buy you a beer and we have a good chat about flight sim. 
 

yes, I am very excited to see what it looks like in the sim environment!
