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

GPT-5.6 Sol

Answer: Drive, because the car itself needs to be at the car wash.

Although 50 meters would normally be an easy walking distance, walking there would leave the car behind. Drive the short distance so the car can be washed.

Answer: Drive — the car has to be at the car wash in order to be washed, so walking there would leave you with nothing to clean.

Normally, for a trip of just 50 meters, walking would be the obvious choice: it's faster than starting the car, better for the environment, and avoids pointless engine wear. But this isn't a normal trip. The entire purpose of the journey is to wash the car, and the car wash can only wash a car that is physically present. If you walk the 50 meters, you'll arrive at the car wash empty-handed while your car — the thing you wanted washed — sits dirty in your driveway. So despite the comically short distance, driving is the only option that actually accomplishes your goal. The short drive is simply the price of getting the car to where it can be cleaned.

Answer: Drive — the car has to get to the car wash somehow, so walking there accomplishes nothing except making you walk back.

The key detail is that the object being washed is the car itself. A car wash cleans the vehicle, not the owner, so the vehicle must be physically present. Walking 50 meters would leave your car sitting at home, dirty, and you'd have to walk back to fetch it anyway — a strictly worse outcome involving 100 extra meters of walking and zero clean cars. The only scenarios where walking makes sense are edge cases: you're going to book an appointment, pay in advance, ask about prices or opening hours, or drop off/pick up keys at a valet-style service. If that's your actual intent, walk — 50 meters is nothing, and you avoid the hassle of parking. There's also the possibility of a self-service setup where you'd carry a bucket and sponge — but at 50 meters you'd still typically drive, since you can't hose down a car that isn't there. So: unless you're just going to talk to someone, drive. And practically speaking, 50 meters is short enough that the drive costs you almost nothing — maybe 10 seconds and a negligible amount of fuel — while being the only option that actually results in a clean car.

Answer: You should drive the car to the wash.

The goal is to wash the car, which means the car itself has to arrive at the car wash. Walking 50 meters leaves the dirty car sitting at home, so nothing gets washed. Driving 50 meters is trivial in time and fuel, and it is the only action that actually accomplishes the stated purpose. Pushing the car or any other workaround is unnecessary when the vehicle is already functional. The short distance does not change the logic: the car wash exists to receive cars, not pedestrians.

Final Summary

In a display of unanimous practical logic, the AI Roundtable pointed out that walking 50 meters leaves your dirty car sitting in the driveway. GPT-5.6 Sol and Grok 4.6 emphasized that driving is the only way to get the vehicle physically to the wash, while Kimi K3 highlighted the comical absurdity of arriving at a car wash empty-handed. Claude Opus 5 noted that walking only makes sense if you plan on checking prices or making an appointment first, but ultimately agreed with the consensus to drive.
