I agree that phantom braking has "improved". The frequency of the occurrence has definitely decreased during my 2 years/18000 miles of driving my Model Y. But you have to drive with a consciousness that it can occur at any time, particularly when approaching curves or parked vehicles. Usually, an audio warning is given by the car instead -- which is a bit too frequent -- though I have not adjusted its configuration to a higher threshold.
I've used that feature on the Toyotas and the Kia I own. As another commenter pointed out, other brands have the same phantom braking issue, but for the cars I've owned, I've haven't experienced it.
The cruise control on my Kia (MY18 Optima) phantom brakes in certain situations. Typically in curves on divided highways, when you are in the left-most lane. I think it gets confused and panicky by the divider fence.
Luckily there is no OTA or other updates happening to these systems, so I quickly learned to anticipate and never get surprised by it anymore.
Phantom braking is a real issue that I have directly experienced, autopilot is terrible, but I disagree that cruise control is unusable. I have found Tesla's cruise control (without steering), which includes car distance maintenance and braking, to be extremely reliable. It can be problematic at low speeds, but less so than traditional cruise control which does not have sensor informed braking.
My understanding is that some of the top VW group (VW / Audi / Porsche) executives can’t even visit the US for fear of being criminally charged for the dieselgate shenanigans. So add them to your list.
