I want to wash my car. The car wash is 20 metres away. Should I walk or drive

Sonar Pro (changed mind)

Vote: Drive

The core goal is to wash the car, which requires physically transporting the vehicle to the car wash 20 meters away. Walking leaves the car behind, making the task impossible without someone else moving it—defeating the purpose entirely.[1] Arguments for walking overlook this fundamental logic: no car at the wash means no washing. The short distance (20-30 seconds walk) doesn't change the necessity of driving the car there, as confirmed by multiple models like GPT-5.4, Gemini, and Kimi, who prioritize practicality over minor time/fuel savings.[1] Previous vote for A was swayed by irony and efficiency memes, but real-world physics trumps them—the car must be present. Driving is trivial, safe, and achieves the objective; walking does not. This is the practical, non-absurd choice.

Vote: Drive

I maintain vote B: Drive. The key point is the goal, not my personal travel. You want to wash the car, so the car itself must be moved to the car wash. Walking 20 metres gets only you there, not the vehicle that needs washing. The arguments for walking focus on efficiency for a person covering 20 metres. That misses the central constraint: the car must arrive at the wash bay somehow. For this question, "drive" is the only option that actually accomplishes the task. If the intent were merely to visit the car wash, walking would be sensible. But to wash your car, the car has to go too. That is why the pro-walking arguments were not compelling enough to change my position.

Initially, I focused on the inefficiency of driving such a trivial 20m distance—fuel waste, pollution, and time to start the car. However, this overlooks the core objective: washing the *car*. Walking arrives at the car wash without the vehicle, rendering the task impossible. You can't wash a car left 20m behind. All B voters (GPT-5.4, Gemini 3.1 Pro, Kimi K2.5) hammered this logic home clearly: the car must be transported there, no matter the distance. Gemini 3.1 Pro's point was most direct and persuasive, exposing the flaw in 'walk' arguments (mine and Sonar Pro's). Driving 20m is negligible in fuel/time vs. the necessity of getting the car to the wash. It's the only practical choice.

Sonar Pro and Grok 4.1 Fast, you have completely missed the fundamental logical constraint of the prompt: the goal is to wash the car. If the user walks the 20 metres, they will arrive at the car wash on foot, leaving their car parked at the starting point. It is physically impossible to wash a car at a car wash if the car is not actually there. While your arguments about environmental impact, fuel efficiency, and health would be perfectly valid for any other errand, they are entirely irrelevant here. The item that needs the service is the vehicle itself. Therefore, driving (or moving) the car to the car wash is the only logical choice to fulfill the objective.

Vote: Drive

The pro-walking arguments fundamentally misunderstand the task constraint. To wash a car at a facility, the vehicle must be physically present at that facility. Walking 20 meters without the car accomplishes nothing—it is a trip to look at an empty wash bay while the dirty car remains parked at home. While driving 20 meters is indeed inefficient and adds trivial wear, it is the only action that satisfies the goal. The efficiency, health, and environmental benefits cited by A-voters become irrelevant when the proposed action cannot complete the task. You cannot wash a car remotely. Therefore, despite the absurdly short distance, driving is the only practical and logical choice to achieve the stated objective.

Final Summary

The AI Roundtable initially split over the absurdity of a 20-metre commute, with Sonar Pro and Grok 4.1 Fast championing the health and environmental benefits of walking. However, a reality check from Gemini 3.1 Pro and GPT-5.4 regarding the physical laws of car washing forced a total collapse of the 'Walk' coalition. The session concluded with a rare unanimous agreement that while walking is virtuous, it is a poor method for transporting a two-ton vehicle to a wash bay.

All 5 models agreed on "Drive" after discussion

Strongest Arguments

• Walk: Walking 20 metres is faster, healthier, and prevents unnecessary engine wear and pollution for a trivial distance.
• Drive: A car wash requires the car to be physically present; walking there results in a person standing at a car wash while their dirty car remains in the driveway.

Key Turning Points

• Gemini 3.1 Pro pointed out the logical absurdity of 'washing' a car that is left 20 metres away from the facility.
• Sonar Pro and Grok 4.1 Fast realized their preference for walking ignored the physical constraint of needing the car at the car wash.
