I want to wash my car at the car wash that is 50m away. Should I walk or drive there?

GPT-5.4

Vote: Drive

I maintain vote B: Drive. The decisive fact is unchanged: the thing that needs to get to the car wash is the car. Walking 50 meters brings only you there, not the vehicle you want washed. Grok’s efficiency point would make sense for a normal errand, but not for transporting the car itself to a service location. Avoiding fuel use is irrelevant if walking fails to accomplish the task. The other B arguments correctly focus on the goal rather than the distance. A 50m drive is silly in isolation, but it is still the only option that actually gets the car to the car wash.

Grok 4 (changed mind)

Vote: Drive

All other models highlighted a key point I initially missed: the goal is to wash the *car*, which requires bringing the vehicle to the car wash. Walking alone leaves the car behind, making the trip pointless and requiring a second journey. This overrides the short distance consideration, as efficiency for the actual task matters more than minimizing a 50m trip on foot. The arguments from the group were consistent and compelling on the core objective.

Vote: Drive

I maintain my vote for B (Drive). The core logic remains unchanged: you cannot wash your car at a car wash if your car isn't there. Walking 50m to the car wash would leave your vehicle behind, making the trip pointless for the stated purpose. Grok 4's argument for walking focuses on efficiency and environmental benefits, but overlooks the practical necessity of having the car present. Those considerations become irrelevant when the primary goal cannot be accomplished. The distance (50m) is indeed very short, but this doesn't change the fundamental requirement: the object being serviced must be at the service location. This is a case where practical necessity overrides all other factors.

Vote: Drive

I am firmly maintaining my vote for B (Drive). As nearly all of us have pointed out, the entire purpose of the trip is to wash the car. Grok 4's argument for walking (A) completely misses the core objective. While Grok is correct that walking 50 meters saves fuel and reduces emissions, walking leaves the car parked at home. You cannot wash a car at a car wash if you do not bring the car with you. Driving is not just a matter of convenience here; it is an absolute physical requirement to accomplish the task. The distance is irrelevant when the object being transported is the vehicle itself.

Vote: Drive

I'm maintaining my position. The logic is straightforward and nearly unanimous among the models: you cannot wash your car at a car wash without bringing your car. Grok 4's argument for walking focuses on fuel savings, emissions, and convenience — all valid points in a normal "should I walk or drive 50m" scenario. But it completely ignores the fundamental constraint: the car must be at the car wash to be washed. Walking there without the car accomplishes nothing. This isn't really a transportation question — it's a logic question. The car is not just your mode of transport; it's the object being serviced. You drive because you must, not because driving is the superior way to travel 50 meters.

Vote: Drive

I maintain my vote for B (Drive). The car must be physically present at the car wash to be washed; walking there without it would require an immediate return trip to fetch the car, doubling effort and time. Grok 4's points about walking being short and eco-friendly are valid in isolation, but they ignore the fundamental inefficiency: arriving without the car fails to accomplish the stated goal. Driving 50m ensures the car is where it needs to be, making it the only logical choice.

Final Summary

The AI Roundtable initially faced a lone dissenter in Grok 4, who argued that a 50-meter trip should be a walk by default, but the model quickly realized the logistical absurdity of leaving the vehicle behind. Led by Claude Opus 4.6 and GPT-5.4, the group successfully argued that a car wash is a physical destination for the car itself, leading to a unanimous 6-0 consensus for driving.

All 6 models agreed on "Drive" after discussion

Strongest Arguments

• Drive: The car is not merely a mode of transport in this scenario; it is the object being serviced, making its physical presence at the destination a non-negotiable requirement for the task.

Key Turning Points

• Grok 4 initially prioritized the 50m distance and environmental impact, voting to walk.
• Claude Opus 4.6 and Gemini 3.1 Pro highlighted that walking would result in arriving at the car wash without the car.
• Grok 4 acknowledged the logical flaw in its initial reasoning and switched to 'Drive' during the discussion phase.
