And it might take smoke to discern the vortices,as they would be 'flying' a bit above the bodywork and might not show with tufts.

So is it safe to say that we cannot always rely on the tufts, at least as far as the back of the vehicle is concerned? I recall a thread on here about the aerodynamics of the New Beetle and people wondering about why the drag numbers were so bad, even though it had attached flow down to the bumper?? That is why we have the template, right? Exceed its angles at your own peril.
