On Nov 14 at 09:01 AM while driving on the freeway with clear weather and autopilot is on for at least 15 min and and i am fully attentive and no traffic the tesla auto pilot decided to turn left and hit the cement barrier of the freeway damaging my left rear wheel then it tried to correct it fault by turning right to the right lane abruptly luckily there was no traffic coming on my right side too otherwise it would have been fatal I have the incident recorded by the sentry mode cameras and exact time and sec and the logs of the car black box proves that the tesla auto pilot was engaged at that time when it hit the cement barrier I reported this to tesla so they would take responsibility of their risky autopilot software but they dont care and told me i can report it to NHTSA it doesnt matter to them even with all the documented proof i have
