THE VEHICLE WAS PLACED IN REVERSE BUT IT WOULD NOT MOVE. IT WAS PLACED BACK IN PARK AND LEFT RUNNING IN MY GARAGE. I GOT OUT OF THE VEHICLE IN ORDER TO LOOK OVER THE EXTIERIOR FOR PROBLEMS; NONE FOUND. I THEN KICKED/PUSHED THE BACK BUMPER AND IMMEDIATELY HEARD A CLUNK, THE VEHICLE WAS THROWN INTO REVERSE AND HEADED AT ME. IT CAUSED A GREAT DEAL OF DAMAGE TO THE VEHICLE, MY OTHER VEHICLE PARKED IN THE GARAGE AND MY HOUSE. I WAS ALMOST RUN OVER BY THIS DRIVER-LESS VEHICLE. I DO HAVE A WITNESS THAT SAW THE VEHICLE CHARGING AT ME.
