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

Answer: You should drive your car to the car wash, as the vehicle itself must be present at the facility to be washed.

While a distance of 50 meters is extremely short and would typically encourage walking for health and environmental reasons, the objective here is to wash your car. If you choose to walk, you would arrive at the car wash without your vehicle, rendering the trip pointless unless your goal was merely to purchase supplies. To actually utilize the car wash's facilities on your vehicle, the car must be physically brought to the location. Therefore, driving is the only practical option to accomplish your goal.

Answer: Drive your car to the car wash, since the car itself needs to be there to be washed.

The purpose of going to the car wash is to wash your car, which means the car must physically be at the car wash. Walking there would leave your car behind, defeating the entire purpose of the trip. While 50 meters is a short distance you could easily walk, the question isn't really about transporting yourself — it's about transporting the vehicle that needs cleaning. You can't wash a car that isn't there. So the answer is clear: drive the car the 50 meters to the car wash. The walking-versus-driving decision only makes sense when you're the only thing that needs to arrive, which isn't the case here.

GPT-5.5

Answer: You should walk to the car wash because it is only 50 meters away.

Walking such a short distance is far more practical and efficient than starting the car for a negligible trip. Driving 50 meters would waste fuel, generate unnecessary emissions, and take roughly the same amount of time once you account for getting in and out of the vehicle. The proximity makes walking the clear choice for both convenience and environmental considerations.

Answer: You should drive to the car wash.

The purpose of going to the car wash is to clean your vehicle, which requires bringing the car itself to the location. Walking would leave the car behind and defeat the objective entirely. At only 50 meters the drive is short, but it remains the only practical option that accomplishes the stated goal.

Final Summary

The AI Roundtable highlights a hilarious case of missing the forest for the trees. While GPT-5.5 passionately argued that walking 50 meters is the superior choice for the environment, Gemini 3.5 Flash, Claude Opus 4.8, and Grok 4.3 pointed out the glaring logistical reality: you cannot wash a car if you leave it parked at home.
