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.
I find Grok's "personality" hilarious, it sounds like a buffed up "chad" who is hitting its 100 bench rep while not breaking a sweat.
That's not reality though. In reality you need 50-100ml of fuel just to warm up the engine.
The real reality is that with direct fuel injection and everything under computer control, warming up the engine isn’t a thing anymore.
Of course it's still a thing. It takes 30 seconds, but it's there and requires energy.
Compare the smell of exhaust next time you do a cold and warm start of a combustion car. That smell is the engine running rich, because the fuel can't initially vaporise properly.
