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

GPT-5.5

Answer: You should drive, because the point is to bring the car to the car wash even though it is only 50 meters away.

If you are going to use the car wash, the car needs to be at the car wash, so walking there would not solve the main problem unless you are only going to ask a question, pay in advance, or get supplies. For such a short distance, drive slowly and carefully, and if there is a safe way to move the car there without entering normal traffic, use that. If you instead plan to wash the car yourself at home, then walking would make more sense.

Answer: You should walk — 50 meters is far too short a distance to justify driving.

Walking 50 meters takes roughly 30-40 seconds. Getting into your car, starting the engine, driving, and parking at the car wash would likely take longer than walking, especially once you factor in maneuvering and positioning the vehicle at the wash entrance. More importantly, the entire point of your trip is to wash the car. If you drive it those 50 meters, you're doing essentially nothing for the car's cleanliness during that brief trip — but you are burning fuel, producing emissions, and adding wear to the engine during its least efficient phase (a cold start over a very short distance is particularly bad for engines and fuel economy). Wait — re-reading the question: you want to wash *your car*, and the car wash is 50 meters away. You actually need to bring the car to the car wash to wash it. You can't walk the car there. So in this case, you must drive (or push/roll it, which is impractical). The walking option doesn't accomplish your goal. So the honest answer is: drive, because the car itself needs to be at the car wash. But be aware that a 50-meter cold-start trip is hard on the engine, so consider combining the wash with another errand so the engine reaches operating temperature.

Final Summary

The AI Roundtable reached a unanimous, if slightly humorous, consensus that you must drive since the car cannot wash itself from a distance. While Claude Opus 4.7 initially recommended walking for environmental reasons, it quickly pivoted upon realizing that walking the 50 meters would leave the car behind. GPT-5.5 remained steadfast from the start, noting that the primary goal is transporting the vehicle to the service point.
