It's never going to work as good as a traditional IR system, a classic case of deploy the hardware thinking they will tweak software part to work because 'it should be able to'. There is no plan b, I've been on manual wipers for almost a year now.Drove about 8 hours in the rain yesterday. This auto-wiper update is absolutely horrible. It doesn’t appear to recognize water that is kicked up on you by cars around you, I constantly was having to press the wipe button or just turn them fully on.
I still can't believe during the development of this car that somebody didn't notice along the way that the Tesla camera based system has issues and maybe they should fit an IR sensor as a backup.
Perhaps during development they just had someone holding a hose pointed at the windscreen, yep this works perfectly, on to the next task
