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

GPT-5.2 (changed mind)

Vote: Drive

Driving is necessary because the goal is to wash the car, and the car itself must be at the car wash bay for that to happen. Walking 50 meters only transports you, not the vehicle, so it fails the objective unless the scenario implicitly meant “walk to where the car is parked at the wash already,” which isn’t stated. The distance-based efficiency arguments (fuel, wear, convenience) are secondary to feasibility: you must move the car to the wash, and among the given options, “Drive” is the only one that accomplishes that.

The purpose is unequivocally to wash *the car*, which requires physically bringing it to the car wash 50 meters away. Walking arrives empty-handed, leaving the car dirty at home—mission failed. GPT-5.2's lone A argument falters: it imagines 'leaving it parked' as strategic to avoid 'fresh road dust,' but that's nonsensical; the car stays unwashed regardless, and you'd still need a return trip to fetch it. No dust avoidance justifies futility. Driving 50m takes ~10 seconds, burns ~0.001L fuel (negligible vs. idling), positions the car perfectly in the bay/track, and carries supplies effortlessly. Pushing? Absurdly laborious/risky over smooth driving. Health/eco gains from walking are illusory without the car; B is the only rational, practical choice. Consensus of 5/6 models affirms this—don't be swayed by the outlier.

Vote: Drive

My position remains unchanged. The question is fundamentally about logistics, not about the healthiest or most environmentally friendly way to travel 50 meters. The goal is to wash your car. A car wash washes cars that are physically present at the car wash. If you walk there, you arrive without your car, and your car doesn't get washed. GPT-5.2's argument about avoiding 'fresh road dust' from driving 50 meters, or saving fuel, completely misses the point — those concerns are trivially irrelevant compared to the fact that walking means you literally cannot accomplish your stated goal. GPT-5.2 even acknowledges this implicitly by framing it as a personal transportation question ('walking is the simplest choice'), but the question isn't about transporting yourself — it's about transporting your car to be washed. The overwhelming consensus (5 out of 6 models) correctly identified that driving is the only answer that makes logical sense given the objective.

Vote: Drive

I am firmly maintaining my vote for B (Drive). While GPT-5.2 makes valid points about engine wear, fuel savings, and road dust in the context of a standard 50-meter commute, it completely overlooks the fundamental premise of the prompt: the objective is to wash the car. If you walk to the car wash, you arrive without the very object you intend to wash. You cannot wash a car that is parked 50 meters away. Driving the car to the facility is a functional prerequisite to achieving the stated goal. Therefore, despite the exceptionally short distance, driving (or otherwise physically moving the vehicle) is the only logical and possible choice.

Vote: Drive

I maintain my vote for driving. The fundamental logic remains unchanged: you cannot wash your car at a car wash if your car isn't there. Walking 50 meters would get you to the facility, but leave the very object you intend to wash parked at home. GPT-5.2's argument for walking fails to address this core contradiction—it suggests leaving the car parked to avoid road dust, but this makes the entire trip pointless since you'd arrive without the vehicle that needs washing. The distance is irrelevant to the mode of transport in this case; the objective itself dictates that the car must accompany you. All other models correctly identified this logical necessity. This isn't about efficiency or environmental considerations—it's about whether the stated goal can even be accomplished. Driving is the only option that allows the car to be present at the car wash, making the task possible to complete.

Vote: Drive

I maintain that driving is the only viable option because the explicit goal is to wash your car. The fundamental constraint of this task is that the car must be physically present at the car wash to be washed. Walking 50 meters to the facility without the vehicle accomplishes nothing toward the stated objective—you would arrive at the car wash without the car, making it impossible to complete the task. While GPT-5.2's argument for walking correctly notes that 50 meters is a short distance that normally favors walking, it fails to address the critical flaw: you cannot wash a car that remains parked at home. The argument that driving adds 'fresh road dust' is irrelevant because the alternative (walking without the car) results in zero possibility of washing the car at all. The mode of transport must be determined by the task requirements, not just distance efficiency. Driving 50 meters uses negligible fuel and is the only action that actually positions the car where it needs to be for cleaning.

Final Summary

The AI Roundtable initially faced a minor logic crisis when GPT-5.2 prioritized engine health and exercise over the basic physics of the task. While the rest of the group, led by a pragmatic Claude Opus 4.6, pointed out that one cannot wash a car that isn't there, GPT-5.2 eventually conceded that walking 50 meters to a car wash empty-handed was a 'failed objective.'

All models agreed on B after discussion

Strongest Arguments

• Walk: At only 50 meters, walking avoids unnecessary engine start/stop wear and eliminates the hassle of maneuvering for a trip that takes less than a minute.
• Drive: The fundamental goal is to wash the vehicle; walking to the facility without the car renders the entire trip pointless regardless of the short distance.

Key Turning Points

• GPT-5.2 initially focuses on the health and environmental benefits of walking a short distance.
• Claude Opus 4.6 and Gemini 3.1 Pro highlight the logistical impossibility of washing a car that remains parked at home.
• GPT-5.2 switches its vote in Round 2, acknowledging that the 'car' part of a car wash is mandatory.
