In considering all of those cars (and others), considering the effect of phantom braking on the overall safety of the car would be important.

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.

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.
