I want to wash my car. The car wash is 20 meters away. Should I walk there, or drive there

Claude Opus 4.7 (changed mind)

Vote: Drive

I'm changing my vote. The other models make a decisive practical point I underweighted: the entire purpose of the trip is to get the car to the car wash. If I walk, I arrive without the car — and have nothing to wash. The car must physically be at the car wash to be cleaned. My original reasoning treated this as a generic "should I walk or drive 20 meters" question, but context matters. You can't wash a car that's 20 meters away from the car wash. Walking yourself there accomplishes nothing toward the stated goal. The minor downsides of driving (fuel, cold start, tire dirt) are trivially outweighed by the fact that driving is the only option that actually achieves the objective.

Vote: Drive

I maintain my vote for "Drive". The key fact is not the distance but the goal: "I want to wash my car" at a car wash 20 meters away. To use the car wash, the car itself must be there. The arguments for "Walk" correctly note that 20 meters is trivial for a person, and driving such a short distance is normally inefficient. But they do not solve the central problem: if you walk there without the car, you arrive at the car wash with nothing to wash. Unless the plan is to carry supplies back or physically push the car, "Drive" is the practical answer.

Claude Opus 4.7 and Grok 4.3 argue about fuel efficiency and the health benefits of walking, but they completely miss the physical reality of the task: you cannot wash your car at a car wash if your car is not there. While Claude Opus 4.7 acknowledges that the car needs to be brought to the location, the suggestion to "walk the car over" is absurd—you cannot walk a two-ton vehicle on a leash like a dog. The only way to "walk" a car is to put it in neutral and manually push it, which is incredibly strenuous, impractical, and potentially dangerous. The premise of the question is not about traveling to a location; it is about taking your vehicle to a facility to be washed. The standard, safest, and most logical way to transport a car, even for 20 meters, is to drive it. Therefore, despite the unusually short distance, "Drive" is the only option that actually allows you to accomplish your goal.

Grok 4.3 (changed mind)

Vote: Drive

The goal is to wash the car, which requires the vehicle itself to be at the car wash. Walking there leaves the car behind, making the task impossible. I was convinced by GPT-5.5's clear point that the car must physically arrive to be cleaned.

Final Summary

The AI Roundtable was initially deadlocked when Claude Opus 4.7 and Grok 4.3 argued that a 20-meter trek was better suited for a brisk walk than a cold start. The tide turned instantly when Gemini 3.1 Pro and GPT-5.5 pointed out the logistical absurdity of arriving at a car wash without a car. Realizing that one cannot realistically put a two-ton sedan on a leash, the dissenters abandoned their environmental concerns to favor the only option that actually involved a vehicle.

All 4 models agreed on "Drive" after discussion

Strongest Arguments

• Drive: The goal is to wash the car, which requires the vehicle to be physically present; walking yourself to the location accomplishes nothing toward the objective.
• Walk: Driving a mere 20 meters is inefficient, wastes fuel, and subjects the engine to unnecessary wear for a distance that takes less than thirty seconds to walk.

Key Turning Points

• Gemini 3.1 Pro and GPT-5.5 pointed out that the prompt's goal is to wash the car, not just for the person to arrive at the location.
• Gemini 3.1 Pro highlighted the impossibility of 'walking' a car like a dog, dismantling the idea that a person could walk while still bringing the vehicle.
• Claude Opus 4.7 and Grok 4.3 conceded that the specific context of a car wash overrides general advice against short-distance driving.
