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

Gemini 3.5 Flash

Answer: You must drive, because you cannot wash your car at the car wash if you walk there and leave the vehicle behind.

Although 50 meters is an incredibly short distance that would normally warrant walking for any typical errand, the objective here is specifically to wash your car. If you choose to walk to the car wash, your vehicle will remain parked at home, making it impossible to actually wash it. To utilize the car wash, the vehicle itself must be transported to the facility. Therefore, driving the car the short 50-meter distance is the only logical choice to accomplish your goal.

Answer: You should drive your car to the car wash because the vehicle needs to be transported there for washing.

Walking 50 meters is a short distance, but it would leave your dirty car at home, defeating the purpose of visiting the car wash. Driving allows you to bring the car directly to the service, making the trip practical and efficient despite the proximity. Fuel or environmental concerns are minimal for such a short drive, and walking would require an unnecessary extra trip later.

Answer: You should drive, because the car itself needs to get to the car wash.

Even though 50 meters is normally an easy walking distance, the purpose of the trip is to wash the car, so walking there without the car would not accomplish the goal. If you only need to check whether the car wash is open, pay in advance, or buy supplies, walking would be fine. But if you are actually going to use the car wash, drive the car the short distance.

Answer: You should walk to the car wash, since 50 meters is a trivial distance and driving would be wasteful and counterproductive.

Fifty meters is roughly a 30-second walk — shorter than the time it would take to get in your car, buckle up, start the engine, and park at the destination. Driving such a short distance would burn fuel inefficiently (cold engines are at their least efficient in the first minute), add unnecessary wear to your starter and engine, and emit disproportionately high pollution for the distance covered. There's also a practical irony: you're going to *wash* the car. If you drive it 50 meters on a public road, you risk picking up dust, mud, or road grime along the way — partly undoing the point of the trip. Walking lets you arrive at the car wash with the car in the same state it's currently in (assuming you're washing it yourself with equipment there) or simply enjoy a brief walk before driving it home clean. The only edge cases where driving makes sense: if it's an automated car wash that requires you to drive the vehicle through it (in which case you obviously must drive the car there), if the weather is severe, or if you have a mobility limitation. Assuming none of those apply, walk.

Answer: You should drive your car to the car wash because the purpose of the trip is to wash the vehicle, which requires the car to be physically present at the facility.

Fifty meters is roughly a one-minute walk for a person, so driving such a short distance is admittedly suboptimal for your engine—oil will not reach full operating temperature, fuel combustion will be less efficient, and you will produce unnecessary emissions. However, the goal is not simply to travel to the car wash, but to wash your car. Unless the facility offers a mobile service that comes to your location, the car must be moved into the wash bay, and walking there without it would leave you unable to complete the task. If you are concerned about engine wear, you could minimize harm by driving slowly and combining this trip with a longer errand, but given the explicit constraint, driving the car is the only practical way to get both you and your vehicle to the destination. Therefore, despite the brevity of the trip, you should drive.

Final Summary

The AI Roundtable largely prioritized the practical necessity of the task, with Gemini 3.5 Flash, GPT-5.5, Grok 4.3, and Kimi K2.6 all noting that the vehicle must be physically present at the car wash. Claude Opus 4.7 provided a sharp dissent, arguing that driving 50 meters is environmentally wasteful and mechanically inefficient for the engine. While the group acknowledged the distance is walkable, the majority concluded that walking without the car defeats the entire purpose of the trip.
