Hi Morris. You are right. Well, we're both right.

The air flow is disturbed by the wheel arch and the spinning wheel/tire, and separates from the body.

That puts the boundary layer into a series of vortexes over the vent area. Without actual smoke testing we might only be guessing what is happening to the air movement in the vent.

I'll tuft test it his weekend if it doesn't rain.

A vent in the hood a an excellent alternative.
