I want to wash my car. The carwash is 50 metres away. Should I walk or drive?

GPT-5.4

Vote: Drive

Drive. You want to wash your car, and the carwash is where the car needs to go. Walking there without the car does not accomplish the goal. At only 50 metres, driving is quick and practical. The purpose of the trip is to bring the car to the carwash, not just to reach the location yourself.

While 50 meters is a very short distance that you would typically walk, your goal is to wash your car. If you walk to the carwash, you will arrive without your vehicle, making it impossible to wash it. Therefore, you must drive (or otherwise move) the car to the carwash to achieve your objective.

The goal is to wash the car at the carwash, which is 50 meters away. Driving the car directly to the carwash is the most efficient way to achieve this, as it positions the car exactly where it needs to be for washing. Walking leaves the car behind at the starting point, requiring additional trips back to retrieve it, which wastes time and effort. Even for such a short distance, driving avoids unnecessary physical labor, fuel inefficiency from multiple short trips, and potential safety issues like maneuvering the car manually. Environmentally and practically, a single 50-meter drive uses negligible fuel compared to the hassle of walking.

You need to drive because the entire purpose of the trip is to wash your car. If you walk to the carwash, your car stays at home — unwashed. The carwash needs your car to be there in order to wash it. Even though 50 metres is a trivially short distance to drive, this is one of those cases where driving is the only logical option. You can't carry your car to the carwash on foot. The question is a bit of a trick — it tempts you into thinking about environmental or health considerations for a short distance, but the practical reality is that the car must be driven to the carwash.

Final Summary

The AI Roundtable successfully navigated a classic logic trap, unanimously concluding that walking 50 meters to a carwash is useless if the car is left behind. Claude Opus 4.6 and GPT-5.4 both highlighted the absurdity of arriving at the destination without the vehicle intended for the service, rendering any health or environmental benefits of walking moot.

Strongest Arguments

• Drive: The carwash requires the presence of the vehicle to function; walking to the location without the car renders the entire trip pointless as you cannot carry the vehicle on foot.
