Do you wash your plates or cutlery after use? After all, they will only get dirty again.
Dirt and especially salt can damage the bodywork which can mean an MOT fail. Accumulated brake dust within the wheels can cause brakes to squeal and not perform to their specifications. Dirty headlamps, tail lights and number plates are also liable to see you receive a fine from the police.
Plus a clean car looks good even though you know you it will get dirty again.
Not a good analogy. There are hygiene reasons to keep everything in my house spick and span, but much like I don't wash my house roof or the brick walls, I don't wash the outside of my car. I do wash the alloys for the reason you say, but the rest must be self cleaning, never needed to clean the number plate or lights, maybe the Japanese make them self cleaning like my rear window is alleged to be?
As I sit on the inside who cares about the outside!
