On our Model Y the whipers start whiping like crazy sometimes when its especially sunny. I suspect residues of dirt on the camera facing the sky which distorts the light so the car thinks its water on the wind shield. What a bad idea to use a camera to detect water when there are rain sensors available since decades and those work perfectly fine.

Long story short: auto mode is rubbish.

Works fine for me in Voyager. Long press the image, then select „Save to photos“.
