We had a lot of precipitation in the SF Bay Area this winter and the wiper auto performance left a lot to be desired. I noticed that it had a hard time with drizzle, something we specialize in here. Similarly, when it’s not raining and other cars’ tires kick up a lot of drizzle/sprinkle the entire windshield can go hazy without a peep from the wipers.
I thought by pressing the button to make it go manual, the system would get the message but it’s clear it’s not set up to take user input into account yet.
