Granted, there are probably cases where something else is influencing it, and making it low pressure, but i have not seen it.

Right, but it's nearly always modeled as the hood running into the windshield as if it's a simple obtuse-angled corner, ignoring the void area that is recessed towards the front of the car and under the rear of the hood. And the influence of an engine bay that has trapped a lot of air that wants to escape is also generally ignored. The Corvette example I pointed to earlier, while it is a different car, demonstrates that the high pressure area doesn't necessarily have to travel below the hood line and towards the front of the car. I'm not trying to say that I'm right, because I do understand your point. I just haven't seen enough to convince me it is 100% factual in this case.
