After installing Software version 2024.45.25.15 (Full Self Driving software 12.6.2) on my 2020 Tesla Model Y with Autopilot Hardware v3, I experienced unsafe behavior by the autopilot/automatic safety system. On my second drive after the software update, I was unable to engage the autopilot system. Two Phantom cars appeared on the full self driving visualization. One phantom vehicle was on the left side of the vehicle in my blind spot. A second phantom vehicle was shown about 20 feet ahead and 50 feet to the left of my vehicle. (See screen shots). When I attempted to turn left, the automatic lane keep and blind spot warnings took over and attempted to avoid the phantom vehicle. I was able to override the system, but it caused repeated alarms and attempts to move the vehicle back into the lane.
