> That's for safety if a flake of dirt or dust lands on the front window right over where one of the cameras are, it will do a wipe and try to get rid of the thing

Not that dry conditions. I live in Trondheim, where it rains/snows well over 200 days a year, so it's not wiping off some dry dust of the camera area. It just starts wiping the clean window in perfectly fine weather. At other times it rains quite a bit and it does not come on.

The software update to soft click the left stalk to engage the wiper menu via the left steering wheel roller is a nice quick fix for these situations, so they are doing something.
