"Why don't you open the window." then, is completely obvious to a normie, "why don't you ... " being simply a memorized phrase used to polite suggestions, while for autist it's obviously a question. Autist will eventually learn that this is not what it really means, but it just isn't clear why anybody would want to speak that way, with such pointless complications. For the normie it doesn't matter, it's just what they memorized, words working little more than a mnemonic, rather than something that determines the meaning. They may know from school it's an interrogative sentence and how you're supposed to ask questions, but that doesn't matter to them and not how they intuitivelly process the sentence.
Another problem is that when normies don't have any memorized phrase how to say something, they just can't, leaving the autists confused why they just don't say so, instead of trying to giving nonverbal 'hints', and being passive agressive.
From the other side, autists say thing that nobody else says, leaving the normies confused and letting them guess at the meaning of the phrase that doesn't match anything they have memorized.
