Well, I don't think you get my point based on your last question. My point is that there is no logical fallacy in the car wash question, just like there is none in 2+2. How is it any more logically flawed than asking, "I want to shop for groceries. The shop 50 meters away. Should I walk or drive?".

You’re conflating it being a question granting making it logically sound. The prior context in the question is what adds the logical fallacy to it, the question without that is fine but given the information about the car it becomes absurd. Your new example illustrate different things, context cannot be ignored here as it is what makes the entire thing what it is. In the car wash example, the context has a direct relationship with the question that determines the answer, the relationship matters so much that OP claims that for its benchmark purposes only “drive” is the valid answer. That special condition is what makes it a puzzle, a test, and a logically flawed proposition to test your attention despite it being structured as a question grammatically. 2+2 does not bring this relationship in its structure and presentation.
