On November 30 at 6pm I was driving north on I-75 in the Tampa area with Navigate on Autopilot activated. I was in the middle lane, it was dark, and there was lots of traffic. My screen asked me to confirm the autopilot request to move to the left lane. I tapped the stalk to confirm. I did not look in the left lane and was not controlling the steering, though my hands were on the wheel. The car immediately turned into the left lane and side swiped a police vehicle. Nobody was injured and the damage to both cars was minor. Previously I had received alerts that my left pillar camera was "blocked", but the alerts went away, so I assumed that there was no problem. When the alerts appeared, auto steer was deactivated, but when the alerts went away auto steer worked again. I do not remember when the first alert appeared, but probably earlier in November 2021. Subsequently, the alerts have appeared and disappeared. I have requested service from Tesla, but the appointment is scheduled for next month. The officer in the police vehicle and two other officers who came to the scene looked at my vehicle and took pictures. I received accident report, Crash Number [XXX] from Hillsborough County Sheriff's Office (Case Number[XXX]), but no citation.
