7 Forward Collision Avoidance problem of the 2016 Tesla Model S

Failure Date: 01/04/2018

At approximately 9am on the morning of 1/4/18, I was driving in autopilot on the 405 heading north to my office in santa monica in my Tesla Model S and the car simply ran into the barrier wall on the left side of the car pool lane at 75mph. It was absolutely crazy! I have contacted Tesla about the accident several times, but they are simply not interested. I just read about an accident that the u. S. National transportation safety board is investigating where the same thing happened and the driver died. I believe my accident could have ended the same way and I think it needs to be taken very seriously.
