"The air going under the car takes a straighter path to the rear than the air going around or over the car and according to Bernoulli's theorem,it's pressure would be higher than those other two pathways.-------------------------"

If the path for the air from the front stagnation point to the low pressure zone at the rear is very smooth, the pressure difference, along with the restriction from the ground, can move the air as quickly as the air going around. This is one of the major techniques to produce downforce for racing - the venturi bottom.
