Fresh air straight from the window is nice sometimes. At low speeds it’s nice to crack a window open in spring when it’s like 10C or so. At high speeds an open window becomes annoying and creates drag (to the point that if you need cooling, AC wastes less fuel). Plus at high temps it won’t do anything to cool you down anyway. But low speed, medium temperature - hell yeah I’m opening the window.
