5) all the low pressure of the suction peak can be overwhelmed by the high local static pressure acting at the nose and tail.

We can very quickly see that you have not measured aero pressures on real cars on real roads (or if you have, you've forgotten what you did) when you write stuff like that!
For example, I don't know of even one road car that has a high vertical downwards force at the nose. And as for pressures at the area of the roof apex not impacting lift, well....
