Situation: a car moving quickly down the road with a window open.
Car reference frame: the air outside is moving, thus has lower pressure, thus the air inside the car will be sucked out the window.
World reference frame: the air in the car is moving, thus has lower pressure, thus the ambient air will be sucked into the car.
So, question: if you're in the car, and thus you experience that the outside air has lower pressure, why is the outside air being sucked into the car (due to the outside air's "higher pressure" with respect to the car's air)?
