It's not, we just have a vocal minority here that keep banging on about the same gripes, there is a handy feature to block people though.
Auto wipers work perfect well in the rain during daytime, they are ok but not great in the dark, and currently do seem to sometimes get a bit carried away when really they should stop. They are easily better than my previous 2012 BMW, but that was well behind the times.
Auto Dip Headlights also work perfectly well, I really struggle to see what the issue is people have. Some say they did for reflections from some roadsigns, not something that bothers me much. They aren't matrix headlights like you would get by adding several thousands of extras onto other cars, but we know that when buying.
Auto Pilot is also far better on motorway's than anything else I've tried, including recent MobileEye solutions. Using it off the motorway isn't great, it's not recommended by Tesla and can be pretty terrifying. I use AP (with FSD for lane changes) on a motorway every day, like many things it takes a while to get used to quite how to use it, but then it's like nothing else. Phantom braking seems to get used as a generic term for anytime the car brakes and the driver didn't see why, it's incredibly rare for me, like I think once in the last 10K miles. I think there is a lot of difference depending on people's driving style, I'm very passive, keep the maximum follow distance, and generally stick at about the speed limit.
