The Tesla Model Y automatic dimmer is quite stupid. It dims whenever my lights reflect off a street sign and no other cars are nearby. I have to keep it turned off and dim my lights manually, which is a PITA because sometimes I forget and blind oncoming drivers.
The automatic wipers are even worse: They frequently come on when it's not raining and they don't come on when it is. Yet somehow the automatic wipers on my 2011 Audi work perfectly. WTF?
The automatic wipers on non Tesla cars use infrared sensors that have existed for decades, so they're a well known quantity. The Tesla wipers use the front cameras to detect rain, and those cameras are focused at a distance that's far enough to be able to see other vehicles, so they're not focused on the windshield, which is why they're unreliable.
