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

GPT-5.2

Vote: Drive

Drive. Since you’re washing the car, you need the car at the car wash; it’s impractical to walk there without the vehicle. At 50 meters, the fuel/time cost is negligible, and driving avoids carrying any supplies and ensures the car is positioned correctly for the wash bay/queue.

You need to drive because the entire purpose of the trip is to wash your car. If you walk to the car wash, your car stays at home and doesn't get washed. You need to bring your car to the car wash — that's the whole point. Even though 50 meters is a trivially short distance to walk, walking defeats the purpose since the car wash needs the car to be physically present. You must drive the car there so it can be washed.

You should drive because the purpose of your trip is to wash your car. The car needs to be physically present at the car wash in order to be washed. If you walk 50 meters to the car wash, your car would remain at home, defeating the entire purpose of the trip. While 50 meters is indeed a very short distance that would normally be walkable, the logical necessity of bringing the car to the car wash makes driving the only practical option that accomplishes your goal.

In order to wash your car at the car wash, the car itself needs to be there. If you walk, you will arrive at the car wash without your car. Therefore, despite the short distance of 50 meters, you must drive the car to ensure it actually gets washed.

To wash the car at the car wash, the car must physically be brought to the car wash location, which is 50 meters away. Walking would mean leaving the car behind at its current location, rendering it impossible to wash the car there. Driving the car the short distance ensures the car arrives at the car wash for washing. While 50 meters is very close (roughly the length of half a city block), the purpose requires transporting the car itself, making driving the only practical option. Environmental or exercise concerns are secondary to achieving the goal.

Vote: Walk

Fifty meters is approximately a one-minute walk—roughly the length of half a football field. Driving such a short distance is inefficient: it takes longer to start the engine, buckle up, and find parking than to simply walk. Walking also avoids unnecessary fuel consumption, cold-start engine wear, and emissions for a trivial distance. Unless there are specific mobility limitations or extreme weather conditions not mentioned, walking is faster, healthier, and more environmentally responsible.

Final Summary

The AI Roundtable faced a deceptively simple question that nearly everyone correctly identified as a logistical trap. While GPT-5.2 and Claude Opus 4.6 led a five-model coalition pointing out that a car wash requires the physical presence of a car, Kimi K2.5 stood alone, stubbornly advocating for the efficiency of walking fifty meters while apparently forgetting the vehicle entirely.

Models gave different answers

Strongest Arguments

• Walk: Driving 50 meters is inefficient as it takes longer to start the engine and buckle up than it does to complete a one-minute walk.
• Drive: The purpose of the trip is to wash the car; walking to the car wash leaves the car at home, rendering the entire endeavor impossible.
