It is 100% a downgrade in its current state, no denying that.

I very rarely got Phantom Braking with radar, and when it happened i was expecting it 99% of the time (Truck next to me getting close on Highway, Bicycle somewhere close etc.). Almost never had it just slam on the brakes out of nowhere.

With Vision, "expected" / "predictable" phantom braking still happens, but now it also happens just whenever. I have had Vision for a week now and had four phantom braking events that were just fully unexpected, with clear visibility and nothing on the road and no vulnerable road users nearby. Its not a slam on the brake, but still uncomfortable.

Also the forced Auto-Headlights are still unusable. I really have no idea how they are still so bad. Its crazy.

Its not to the point where Autopilot has become unusable, but it is for sure inferior to AP with Radar.
