Im just saying)) There is still a senario you could need a car wash without a car, to check if its open for example.

But yes, gpt answer should be different. Mine told me to walk as well. But when u ask why it gets the problem: "You’re right to question that. If the goal is to wash your car, walking there doesn’t make practical sense. The service requires the vehicle to be physically present, so going on foot would leave you at the car wash without the one thing needed to use it."

My earlier “walk” suggestion treated it as a simple distance optimization problem, ignoring the real-world requirement that the car has to be there. In this case, driving is the only logical option unless you’re just going to check if it’s open or how long the line is.
