Answer 1

If air comes in it creates an overpressure in the car, which has to go somewhere. So air comes in and goes straight out after. This makes the horrible „wub-wub“ sound. So if you want your air to come in evenly, you have to open a second window, preferably in the back to get rid of the overpressure.

Edit: This is also the reason your ears sometimes pop when you open your window.
