MY TESLA WHEN ON AUTOPILOT ON A FREEWAY RUNNING LESS THAN 5 MPH DUE TO TRAFFIC WAS RIGHT BEHIND A BIG TRUCK AND THE CAR NEVER STOPPED AND BUMPED INTO THE TRUCK. AN ATTEMPT TO BRAKE MANUALLY WAS DONE BUT THE AUTOPILOT WOULDNT DEACTIVATE AND GIVE US BACK THE CONTROL TO STOP THE CAR. I HAVE A VIDEO FROM MY FRONT CAM WITH THE INCIDENT. I WAS LUCKY MY CAR WAS NOT DRIVING AT A HIGHER SPEED IF THE SAME INCDENT COULD HAPPEN AS LIKE MAY OTHERS WHO GOT KILLED.
