So what you are asking is if the air pressure on the top of the car is lower than the sides ( lateral area ) ?
And you are wondering if this is what is causing the vortices and induced drag behind the car ?
Also, you are wondering about effect that the airflow has as it travels from the side of the car body and under the car ?

Am I understanding correctly ?
