There are some good designs which prevent them from getting dirty. For example, Mercedes and VW put them in the rear badge and they're only exposed when needed.

Rear view mirrors are needed all the time. We're not talking about reversing cameras here.

We're talking about replacing mirrors. They're always needed!
