I need to wash my car, but the carwash is only 10 meters away. Do I walk or drive?

Sonar Pro

Vote: walk

Walking is the optimal choice for a 10-meter distance to the carwash. At normal walking pace, this distance takes roughly 15-20 seconds on foot, whereas driving would require time to get into the car, start the engine, navigate to the carwash, find parking, and exit the vehicle—easily adding 2-3 minutes of total time. Walking also eliminates fuel consumption, parking hassles, and environmental impact for such a minimal distance. Unless there are specific constraints like severe weather, physical mobility issues, or heavy items to transport, walking is faster, cheaper, and more practical.

Drive. You need to wash the car, and the carwash is for the car, not for you. If the carwash is 10 meters away, moving the car there by driving is the direct and practical choice. Walking would leave the car behind unless you are pushing it, which makes little sense for such a short distance. A very short drive is still the simplest way to get the car into the wash bay.

The goal is to wash the car at the carwash, which is 10 meters away. To achieve this, the car must be brought to the carwash location. Walking leaves the car at its current spot, unwashed. Driving transports the car the short distance efficiently. 10 meters is negligible for driving—no significant fuel waste, emissions, or effort—making it the practical choice.

You must drive because the objective is to wash your car, which requires the vehicle itself to be present at the carwash. A distance of 10 meters, while short for walking, is too far to practically push a car manually. If you were to walk, you would arrive at the facility without the item that needs cleaning, rendering the trip pointless. Additionally, even for such a short distance, driving ensures you can properly position the car in the wash bay or service area. Attempting to wash the car at its current location (if that were the alternative to driving there) would defeat the purpose of going to a dedicated carwash facility with proper drainage, equipment, and water reclamation systems.

To wash your car at a carwash, the car itself needs to be at the facility. If you walk the 10 meters, you will arrive empty-handed and your car will remain exactly where it is. Therefore, regardless of how short the distance is, you must drive (or otherwise move) the car to the carwash so that it can actually be washed.

You need to wash your **car**, not yourself. The car is the thing that needs to go to the carwash, so you need to drive it there. Even though the carwash is only 10 meters away, walking there without your car defeats the entire purpose — the car won't wash itself. You have to bring the car to the carwash, which means driving it. The short distance is a red herring designed to make you think walking is the obvious, sensible choice. But the practical reality is that the car must be physically present at the carwash to get cleaned.

Final Summary

The AI Roundtable faced a classic lateral thinking puzzle, resulting in a 5-to-1 landslide that favored physics over efficiency. While Sonar Pro took a stand for the environmental and time-saving benefits of walking ten meters, the rest of the group, led by Claude Opus 4.6 and GPT-5.4, pointed out the existential flaw in that plan: a carwash requires the presence of a car.

Strongest Arguments

• walk: Walking 10 meters takes 20 seconds, whereas starting a car, navigating to a bay, and parking takes significantly longer and wastes fuel.
• drive: The 10-meter distance is a red herring; you are washing a car, not yourself, and the car cannot wash itself if you leave it behind to walk.
