We have a 2020 MYLR FSD beta with 44.6 K miles. We experienced many phantom braking events, too many to count. Recently, the Y brake or slow down when a police car or an emergency vehicle is detected by the car cameras. This happens when the emergency vehicle is on the other side of a divided highway or on an adjacent road not connected to the highway. This is annoying, a human driver will never do this braking. Also here in GA, on the highway you have to move over a lane if a police car is stopped on the highway shoulder with its light ON. If you do not, you can be ticketed. The FSD ignore that rule and does not change lane (auto lane change is ON).
