These faux questions always have a valid interpretation that the asker doesn't admit (for some reason). The model is then castigated for not making an opinionated choice
lol, i think the LLM shows more wisdom here than the average person. Functionally, being 50m away from the car wash is at the car wash if you have a dirty car in your possession that needs cleaning. Realistically, the only reason you express the need to go to the carwash if you are in a 50m proximity with your car you intend to clean at the carwash is if you need to walk in and talk to someone.
The question is revealing that the model has a model of language but not of reality. It knows what words go together, but not real-world concepts.
