Hey everyone. I wanted to share a heads up (I have already called Tesla). This morning I was driving to work on the Veteran's Expressway north of Tampa, FL and I had two separate events. The first event occurred where traffic slowed down, I had my autopilot following distance set to 5 (i prefer a defensive, conservative driving style) and the traffic in front of me slowed significantly. The autopilot slammed on the breaks and stopped short of the car in front of me. The car behind me slammed on their breaks and came to a screeching halt as I gave it some gas to not stop short and cause a wreck. The second event occurred northbound on the veterans expressway without any other vehicles around. I was on autopilot going exactly the speed limit (trying to save battery) and the car suddenly gave me an alert, showed a red flashing car touching the front of my car in the heads up display, and slammed on the breaks in the middle of the highway. I turned autopilot off and pressed the gas and proceeded and called Tesla. I updated my firmware 2 days ago. Not sure if that matters. Stay safe!
