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

GLM 5

Vote: walk

Walking 50 meters takes approximately 1 minute and requires zero fuel, produces zero emissions, and involves no parking hassle. Driving such a short distance means cold-starting the engine (which produces disproportionately high emissions), spending time finding parking at the destination, and burning fuel inefficiently. For distances under 500 meters, walking is almost always preferable unless mobility-impaired. The physical activity is beneficial, and you avoid the absurdity of driving a distance that takes longer to get in and out of the car than to simply walk.

Vote: walk

For a distance of only 50 meters, "walk" is clearly the superior option. It takes approximately one minute to walk this distance, whereas driving requires time to enter the vehicle, start the engine, navigate the short route, and find parking—likely taking longer than walking itself. Choosing to "walk" eliminates fuel costs, reduces unnecessary emissions, and provides light exercise. There is no practical advantage to driving such a short distance unless you are physically unable to walk or transporting extremely heavy items, neither of which is indicated in the scenario.

Final Summary

The AI Roundtable overwhelmingly favored option A (walk), with both GLM 5 and DeepSeek V4 Pro arguing that starting a cold engine for a 50-meter trip is inefficient and environmentally wasteful. However, in their zeal to save emissions, both models overlooked a fundamental logistical flaw: if you walk, your car remains parked at home, completely unwashed. Kimi K2.5 timed out, perhaps silently realizing that you cannot wash a car by leaving it in your driveway.

No agreement after 1 rounds of discussion. Final vote: walk: 2

Strongest Arguments

• walk: Driving 50 meters requires a cold start, which produces disproportionately high emissions, and takes longer to park and navigate than a simple one-minute walk.
