And on the flip side, even without thinking, Gemini 3 flash preview got it right, with the nuance of the possibility of getting supplies from the place (which tbh I as a human first thought this was about when I opened this thread on HN).

> Since you are going to the car wash, the choice depends entirely on *how* you plan to wash the car:

### 1. Drive if: * *You are using a drive-through or self-service bay:* You obviously need the car there to wash it. * *You are dropping it off:* If you are leaving it for a professional detailing, you have to drive it there. * *The "50 meters" is on a busy road:* If you have to cross a major highway or there are no sidewalks, it’s safer to just drive the car over.

### 2. Walk if: * *You are just going to buy supplies:* If you have a bucket at home and just need to run over to buy soap or sponges to bring back to your driveway. * *You are checking the queue:* If you want to see if there is a long line before you commit to moving the car. * *You are meeting someone there:* If your car is already clean and you’re just meeting a friend who is washing theirs.

*The Verdict:* If you intend to get the car washed at that location, *drive.* Driving 50 meters is negligible for the engine, and it saves you a round trip of walking back to get the vehicle.
