There is no boundary layer along the side of the car, because of the width of the front tires and fender.....that’s why the yarn is turbulent where the vent is....

The vent on the side of the body is to inboard of the front wheels & fender causing the boundary layer to not be attached to the body at that point....which was why I put the vents up on the hood so the boundary layer could draw the air out of the engine compartment.....thru the vents on the hood.
