Hucho writes that all aerodynamic streamlining has to do with minimizing or eliminating flow separation in the aft-body.This can only be achieved with a very gradual Bernoulli Equation-related deceleration/pressure recovery which will not compromise the turbulent boundary layer,the key to attached,laminar flow,as you mention.Hucho cites Buchheim et al.,and their 23-degree maximum angle streamline contour which agrees favorably with W.A.Mair's 22-degree maximum boat tail contour,which also happens to correlate with the NACA airship body contour research,of which the aerodynamic streamlining template originates.
Automakers don't mind using it to achieve world records,but otherwise appear to hate it.Until Elon Musk reared his beautiful head.
