The wiper system has nothing to do with self-driving -- it's based on total internal reflection in the glass: https://www.youtube.com/watch?v=TLm7Q92xMjQ

Teslas do not use the rain sensors discussed in this video, they use cameras to detect rain.

		Oh good lord, why? This is a solved problem, why would they waste their time on it. Wait, I think I know the answer: Elon's famous (at SpaceX) for saying the most reliable part is no part. So maybe this is a consequence of that. In any case, thanks, TIL!

That's how every non-Tesla works. Tesla's don't do this method which is why their auto wipers have always been so bad compared to everyone else.
