I can understand the difficulty of safely implementing AP functions, but what's the deal with sensing water on the windshield or controlling the high beams? Both of these are really mature technologies and have already been implemented in pre-HW1 Teslas. I was hoping that these two features would be in 17.3.2. They are not. Anyone know why these have not been enabled on HW2 vehicles? I'd really like to try out the wiper feature while it's still raining here in California.
