I WAS PARALLEL PARKING THE CAR ON MY RESIDENTIAL STREET. I WAS IN REVERSE AND PROCEEDED TO BACK INTO THE PARKING SPACE. THE CARS BOTH IN FRONT AND BEHIND ME WERE SOME DISTANCE AWAY. SUDDENLY THE ENGINE REVED TO A VERY HIGH RPM AND THE CAR SHOT FORWARD AND CRASHED INTO THE CAR IN FRONT OF ME. THE CAR WAS STILL IN REVERSE WHEN I TURNED OFF THE IGNITION. SEVERAL PERSONS WITNESSED THE INCIDENT. THEY HEARD THE HIGH REV OF THE ENGINE, AND ALSO NOTED THAT THE BACKUP LITES WERE ON WHEN I HIT THE CAR IN FRONT OF ME. I HAVE OWNED 3 JEEP CHEROKEES AND HAVE DRIVEN THEM FOR THE PAST TEN YEARS SO I AM VERY EXPERIENCED IN DRIVING THIS VEHICLE. I AM POSITIVE THAT THIS CAR WAS IN REVERSE WHEN THE SUDDEN ACCELERATION OCCURRED. *AK
