--- You should drive the car to the car wash, but you should walk yourself.

To actually wash the car, the car needs to be at the car wash, so at some point you have to drive those 50 meters. A sensible approach is:

- Drive the car the 50 meters to the wash bay. - Park or queue as required, then get out and do the wash. - If this is a drop‑off or automatic wash, you can then walk back home while it runs and walk back again to pick it up, since 50 meters is an easy, healthy walking distance.
