I'm going to have to read this, because my knee jerk reaction answer is that it depends on what type of wash you want to give the car. If you want to give the car an actual wash at the car wash, you're going to have to drive it. But if you're wanting to wash it at home, then it doesn't matter how far the car wash is away. Because you can just walk out your front door and grab your water hose. and soap and shit.

I think there are a lot of implicit assumptions in such a short prompt.

Is it a self-service car wash? If not, walking to the attendant and handing them your keys makes more sense.

If it is self-service without queuing, there may be no available spaces/the bay may not be open, requiring some awkward maneuvering.

If you change it to something like:

I want to wash my car. The unattended, self-service car wash is 50 meters away. All of the bays are clear and open. Should I walk or drive? Break each option down into steps, and estimate the amount of time each takes.

You're more likely to get correct responses.
