Well we can agree to disagree on the "proven" technology. My last car had the IR sensor for wipers, and I still had to manually wipe every now and then, ESPECIALLY if the car was parked and I wanted to jump in, start the car, and drive away. Every time I had to wipe the windshield because I don't think the IR sensor realizes when the car is off and then turned on - that rain is even there (just my theory, anyway). This process hasn't changed that I'm aware of, in VWs. My 2016 Golf R had this issue, and my neighbor's 2019 e-Golf behaves identically.
Bottom line is I'm happier with my Model 3 wipers than my IR-based Golf's wipers. I don't doubt your experience with your wipers (way too many complaints on the matter to doubt that, along with the need for a neural net now), but it's not my experience, and I see my fair share of rain here in Seattle!
