Since my Model 3 upgraded to 2019.40.50 (now running 2019.40.50.7) my windshield wipers are randomly running on dry sunny days. They didn't used to do that (say a month ago). It seems to be somewhat related to the front cameras getting glare from low-angle sun but not entirely. Worse this highlights a problem in the car's GUI ... there is no way for the driver to turn the wipers OFF! The other day my car decided it must be raining (on a clear sunny day) and started running the wipers...not just once, but over and over. There's absolutely no way for me to tell the car to stop; I just had to let it streak up and scratch up my windshield until it decided to quit. The decision to use computer vision techniques to replace a $5 rain sensor was one of the worst mistakes in the Model 3 design. I can't imagine how many thousands of person-hours they've wasted trying to find an algorithm that works.
