There are papers which address some of the vehicles listed.
For the others ,the geometric data analytics themselves provide for a high prediction confidence, whether others subscribe to the concept or not. Engineering is guesswork. Like estimating.
A good reason for all the geometric data analytics published for nearly a hundred years now for which to create such a toolbox.
We don't need an authors permission to engineer their work. We don't have to measure anything to predict with high confidence what the actual performance will be.
Ah, back to the template - completely discredited as a means of ascertaining whether a car has attached or separated flow.

So in fact you actually don't have lots of pictures, or tech references, showing all these cars with flow separation?
