    Can someone explain to me why RSWW is so difficult to activate on my EAP? While you're at it. What's the hold up on reading speed limit signs? Seems like pretty old tech to me.

    My suspicion is that they didn't put sensors into the car that can reliably sense rain. The current rain sensor technology uses a special IR optical system to sense wetness on the surface.

    I don't see the reason for not reading speed limit signs, that doesn't sound very hard for machine vision.

    Thanks. Agreed. I thought maybe the camera they need wasn't on yet.

    For automatic windshield wipers, is there a turn off switch? I can see a lot of these wipers being ripped off in an auto car wash.

    Yes.

    Since they had no dedicated rain sensor, they had to implement a neural network to detect what rain looks like on a camera. Not easy.
