I have technical drawings ( it's nearly a miracle if you can find a photograph which depicts dimensions in true-length ) for all vehicles listed, and their geometric parameters. Drag coefficients and CdA will allow reverse-engineering of critical performance. The numbers speak for themselves. The very reason for non-dimensional coefficients in the first place.
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.
