FWIW, my car applies the brakes and swerves, whilst sounding the "klaxons of doom" when neither AP or TACC are engaged, so it's very definitely not just an AP or TACC issue. I can even predict a few places where it will do it consistently. My wife stopped driving the car a few months ago now, because she found the false alarms, sudden application of brakes and the false application of corrective steering input too scary. To be fair, we drive on narrow lanes much of the time, and it seems that the car just cannot cope with roads like this without lots of false alarms. Either way, the sudden application os the brakes (as in a full on emergency stop) is not solely a "feature" of AP or TACC, the car can and will do this when being driven without either of those engaged.
Headlight adjustment is something that has been thrown way out of whack by software updates on my car a few times. I've tried the auto-adjustment feature, but this sets the lights too high, and I get flashed a lot, so I keep taking it to the local garage to get the lights aligned properly. So far I've now had the lights re-aligned three times in the space of a year, but it's only a ten minute job, costs me a tenner each time, but would be free at a Tesla SC I'm sure.
Auto wipers seem reasonably OK in daylight, or perhaps with good street lighting, but frankly they often just fail when it's very dark. Unlike every other car with autowipers, Tesla try to use the cameras for rain detection, and this seems not to work well at all when it's very dark. With no manual wiper stalk control, this means using the touch screen in the dark, perhaps in heavy rain, to try and set the wipers to the correct rate. I find that it's safer to pull over and stop to do this at night. Those that rarely drive down very dark and windy lanes may well not feel that the autowiper issue is significant, for me it's got to the stage that I cannot put up with it any longer.
