I am going to wash my car, but it is only like 20 meters away to the car wash. Should I walk there or drive there?
This is an interesting question to ask LLM powered AIs, the more interesting part is many of them cannot answer this question, even they marked themselves as thinking models.

Given the practical constraints, you should drive the 20 meters to the car wash. Since you need your car at the wash location to wash it, walking there without the vehicle wouldn’t accomplish your goal.

❌
Walk—20 meters is so short that starting and moving the car is mostly just an extra cold start and maneuvering for little benefit. Frequent short-distance operation/cold starts can mean the engine (and oil) doesn’t reach proper operating temperature, which is generally considered harder on the vehicle than a normal warmed-up drive

For a 20‑meter trip to the car wash, it almost always makes more sense to drive there—not to save effort, but because the car wash is only useful if the car is actually on‑site.

✅
Drive your car the 20 meters to the car wash. This is the most practical choice since the vehicle must be at the wash site anyway, avoiding an unnecessary round trip on foot.

For a 20-meter distance (about 65 feet), you should walk there. Here’s why:
Time efficiency: Walking 20 meters takes less than 30 seconds at a normal pace, while getting in your car, starting it, driving, and parking would actually take longer when you factor in all the steps involved.

✅
Given that you are 20 meters away, you should drive your car to the car wash. While 20 meters is a very short walking distance, the car wash requires the vehicle to be physically present in the bay or tunnel to be cleaned.
P.S.
I am not the only one that play around this.
