WHILE PARKING MY VEHICLE AND SLOWING DOWN TO ENTER A PARKING SPACE, I EASED OFF THE BRAKE TO PULL INTO THE SPACE WHEN I HEARD THE ENGINE REV LOUDLY AND THEN THE CAR ACCELERATED AND CONTINUED TO ACCELERATE DESPITE ATTEMPTS TO PUMP THE BRAKES, RELEASE THE BRAKES WITHOUT TOUCHING ANY PEDAL AND ALSO TRYING TO PUT THE TRANSMISSION INTO PARK. THE VEHICLE WOULD NOT STOP AT ALL. I WAS AFRAID FOR MY LIFE AND TRIED EVERYTHING TO AVOID OTHER VEHICLES AND PEDESTRIANS AS THE CAR ACCELERATED GREATLY. I STEERED THE CAR TO TRY AND AVOID A SLIGHT EMBANKMENT AND CURVE BUT WITH THE RAPID SPEED OF THE CAR, IT BECAME HARD TO MANEUVER THE CAR. THE VEHICLE JUMPED THE CURB STRIKING A TREE AND THEN A CONCRETE POST. THE CAR CAME TO REST ON ITS SIDE AFTER IMPACT. THE CAR WAS A TOTAL LOSS.
