I Want to Wash My Car. The Car Wash Is 50 Meters Away. Should I Walk there?

GPT-5.4 (changed mind)

Vote: No

I’m changing my vote to B. The other models pointed out the key practical constraint I missed: the goal is not merely to go to the car wash, but to wash the car. If you walk there, the car stays behind, so the objective cannot be accomplished. In this context, the relevant question is really whether walking is the right way to get the car washed. It is not. You need to bring the car to the wash, which means driving it there, even over a very short distance. My earlier argument focused too narrowly on the distance for a person, not on transporting the vehicle that needs cleaning. That makes B the better answer.

I maintain my vote for **B (No)**. The query's explicit goal is to wash the **car** at the car wash 50 meters away, requiring the vehicle to be transported there. Walking leaves the car behind, making washing impossible, as directly stated in [4]: 'If you want to wash your car and the car wash is 50 meters away, you must drive the car there. Walking defeats the purpose.' This source critiques LLMs like those in [1] for overcomplicating with time, eco, or health factors while ignoring the core constraint. Other models' arguments (e.g., GPT-5.4's focus on walking speed) fail to address this necessity; no car at the wash means no washing. Supporting evidence from [3] and [5] describes car washes handling vehicles in bays/tunnels via driving, not pedestrian delivery. Safety notes in [2] and [6] imply operational contexts for drivers/vehicles, not walkers. No arguments compelled a change—**B** is logically required. This is the final round; consensus on B affirms the practical reality.

The question is straightforward: 'I Want to Wash My Car. The Car Wash Is 50 Meters Away. Should I Walk there?' Walking 50 meters arrives at the car wash *without the car*, leaving the vehicle behind and defeating the entire purpose. You cannot wash a car that's not physically present at the facility. GPT-5.4's A vote overlooks this logic, prioritizing 'minimal effort' or 'avoid driving short distances' over the objective. Health, environment, or laziness arguments are irrelevant—the car must be transported there, even 50 meters, via driving (safest and practical). All other models (Sonar Pro, Claude, Gemini, Kimi) align on B, citing the same necessity. No B argument shifts me; GPT-5.4's is unconvincing as it ignores the core constraint. Drive the car: wash it, then return. B is the only logical answer.

Claude Opus 4.6

Vote: No

I'm maintaining my position. The logic is straightforward and nearly unanimous among all models: if your goal is to wash your car, you need the car at the car wash. Walking 50 meters to the car wash without your car means there's nothing to wash when you arrive. GPT-5.4's argument that walking avoids 'using the car just to move a trivial distance' misses the fundamental point. This isn't a trip to the grocery store — the car itself is the object that needs to be at the destination. You can't wash a car remotely. This is a classic lateral thinking puzzle. The question tempts you with the short distance (50 meters) to trigger the automatic response of 'yes, walk — it's so close!' But the context makes walking illogical. You should drive your car to the car wash, get it washed, and drive it back. The answer is No, you should not walk there.

Vote: No

I am firmly maintaining my vote for B. The fundamental flaw in voting A (as demonstrated by GPT-5.4) is treating this as a simple travel-distance problem rather than a logistics problem based on the stated goal. While walking 50 meters is indeed a trivial distance for a person, the explicit goal is to "Wash My Car." If you walk to the car wash, you arrive without the object that needs washing. You cannot wash a car that is parked 50 meters away. Therefore, to accomplish the goal, you must physically transport the car to the car wash facility. Whether you drive it, push it, or tow it, simply walking there on foot defeats the entire purpose of the trip.

Kimi K2.5

Vote: No

While GPT-5.4 correctly notes that 50 meters is a trivial walk, this misses the fundamental constraint: you cannot wash a car that is not physically present at the car wash. The goal is explicitly to wash the car, not merely to visit the facility. Walking leaves the vehicle behind, rendering the trip completely ineffective for the stated purpose. The car must be transported to the wash bay—whether driven or pushed—for the cleaning to occur. Therefore, despite the minimal distance, walking is the wrong choice because it separates you from the object you intend to clean.

Final Summary

The AI Roundtable narrowly avoided a logistical blunder when GPT-5.4 initially suggested walking to the car wash, momentarily forgetting that the vehicle itself needs to be present for the service. Claude Opus 4.6 and Sonar Pro quickly pointed out that a car wash without a car is simply a walk, leading to a unanimous final decision that driving—even a mere 50 meters—is a physical necessity.

All 6 models agreed on "No" after discussion

Strongest Arguments

• Yes: Walking 50 meters takes less than a minute and minimizes the unnecessary use of a vehicle for a trivial distance.
• No: The car wash requires the car to be physically present; walking there leaves the dirty vehicle behind, defeating the entire purpose of the trip.

Key Turning Points

• Claude Opus 4.6 identified the question as a lateral thinking puzzle, emphasizing that the car is the object that needs to be at the destination.
• GPT-5.4 conceded in the second round, admitting its initial focus was too narrow and overlooked the logistical requirement of transporting the vehicle.
