"The model seems to assume the car is already at the car wash from the wording."

you couldn't drive there if the car was already at the car wash. Theres no need for extra specification. its just nonsense post-hoc rationalisation from the ai. I saw similar behavior from mine trying to claim "oh what if your car was already there". Its just blathering.

This was nonsense post-hoc rationalization from the human who wrote it.
