Nice thread, sort of wish there were extreme examples such as the Aero-Template car and a Pick-Up Truck for comparison.
Is it accurate or ignorant to say/think that avoiding large negative pressures will in turn avoid producing large positive pressures?
That is to say, if you never accelerate the air to begin with, it will not have to slow down later to equalize the mass air flow (correct term?).
EDIT:
The so-called perfect shape would have quite a bit of lift, perhaps we should turn this thing upside down?
