Grok 4.1:

Drive.

50 meters is nothing — literally a 30-second walk or a 10-second drive — but the key point is: your car isn’t going to wash itself.

If you walk to the car wash, you arrive alone. The car stays parked at home, still dirty.

If you drive, the car actually gets to the car wash and gets cleaned.

So unless you’re planning to push the car the whole way (which is technically possible but ridiculous), the only practical option is to drive it there.

Bonus reality check: Driving 50 meters uses a tiny amount of fuel (maybe 0.005–0.01 liters in a normal car) and produces a negligible amount of emissions. Walking would be “greener,” but it literally doesn’t solve the problem.

Verdict: Get in the car, drive the 50 meters, wash it, and drive back.

You’ll have a clean car and still be home in under 5 minutes. Walking is for when you don’t need to move a 1.5-ton vehicle.

Wow, Grok directly switches to LinkedIn mode. Interesting - not surprising. Car washing? Easy as pie.

That's not reality though. In reality you need 50-100ml of fuel just to warm up the engine.
