Yeah I see this argument being made that it’s ambiguous for humans. Uh, no? Why on earth would I walk to the car wash when I want to wash my car?

[sparky_z]

By the same reasoning, why on earth would a person sincerely ask you that question unless the car that they want to wash is either already at the car wash, or that someone is bringing it to them there for some reason?

If it's as unambiguous as you say, then the natural human response to that question isn't "you should drive there". It's "why are you fucking with me?" Or maybe "have you recently suffered a head injury?"

If you trust that the questioner isn't stupid and is interacting with you honestly, you'd probably just assume that they were asking about an unusual situation where the answer isn't obvious. It's implicitly baked into the premise of the question.

The fact that this is so obvious to humans is why there's no training data that LLMs can use to know the answer.

How could the car already be at the car wash if you have the option to drive it there?

You already brought the car there earlier? You bought a new car and negotiated that you get it washed, so you want to collect it? You have a butler? You plan to get someone or something from the car wash to do it at home, because the car you want to wash is dead?
