Full Self Driving was engaged, my hands were on the steering wheel, and vehicle made very unexpected and wrong turn sharply to the right directly into a barrier with front bumper. I have the incident recorded on the dash cam. The time from the sharp turn until the collision was less than 0.5 seconds, not allowing driver response. I have the video of the dashcam recording of the accident. Tesla also has the cabin recording of my engagement during the accident. I cannot send the video through this web page unfortunately
