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

Walk. It's 50 meters — driving there and back takes longer than walking, and you'd just be dirtying the car you're about to clean.

---------> haha but how can i wash my car then?

Walk to the car wash first to check what they offer — many have self-service bays where you bring your car, or full-service where they wash it for you. If it's self-service, then drive over with the dirty car. If full-service, drive over and they handle it.

Either way, the car needs to end up at the wash — the walk was just to scout it out. Or just drive straight there; 50 meters of extra dirt won't matter.

----------> you, you sound like a politician. Are you sure your first answer was really reasoned like your second answer?

You're right, my first answer was nonsense. I pattern-matched on "50 meters = walk" without thinking about the actual task. You can't wash a car without the car being there. Just drive.
