I have it on my car. Learning from this feature from my previous BMW. It's not worth it as it's an annoying feature.
The sensor is the size of a pencil head, the only time the wipers wipe is when a drop of rain hits the sensor. So when it's misty, it might start wiping full speed. And sometimes in shear luck... heavy rain and not a single wipe.
The settings to turn on and off the auto wiper is in the Sync > Vehicle settings. ONLY if you are equipped this function.
