My Tesla Model-x went into 'Sudden Unintended Acceleration' mode, went left to right to left in a violent way, picking up speed like a rocket. I applied the breaks repeatedly, but the car did not stop and continued to race on the road for about 0.3 mile where the road takes slight left turn. It went and crashed into a 40 ft tall big pine tree at probably more than 150 mph. It knocked off part of the compound wall of the owner, and passenger front tire blew away and landed in their front yard. I had the seat belt on. No other vehicle involved. I was the only occupant in the vehicle. No fire. I called 911 from my cell phone. I opened the driver side door manually and got out. Police took the report from me and took pictures.
