This question is obviously ambiguous. The context here on HN includes "questions LLMs are stupid about, I mention boat wash, clearly you should take the boat to the boat wash."

But this question posed to humans is plenty ambiguous because it doesn't specify whether you need to get to the boat or not, and whether or not the boat is at the wash already. ChatGPT Free Tier handles the ambiguity, note the finishing remark:

"If the boat wash is 50 meters down the street…

Drive? By the time you start the engine, you’re already there.

Sail? Unless there’s a canal running down your street, that’s going to be a very short and very awkward voyage.

Walk? You’ll be there in about 40 seconds.

The obvious winner is walk — unless this is a trick question and your yacht is currently parked in your living room.

If your yacht is already in the water and the wash is dock-accessible, then you’d idle it over. But if you’re just going there to arrange detailing, definitely walk."
