Well after 4 months of TeslaVision ownership, I've basically stopped using AP altogether. My neighborhood is connected to our local town by a 2-lane, 45mph country road. I drive this road 3-4 times a day and used to use AP for it because it was relaxing. Now, I find myself with my foot hovering over the accelerator in anticipation of needing to override a phantom braking event, which happens about half the time, both directions, in similar spots. Sometimes it's severe. Usually it's just a drop of 2-3mph then recovers. Both are very annoying. This was one of my favorite features on my '17 M3 and now I hate it. With the '17, it would occasionally get better or worse with software updates over time, but it was never as bad as my '21 TV version is now. My understanding is that the beta FSD code base will eventually merge into standard AP (I don't have FSD) and as far as I'm concerned, they need to do it immediately.
