I BACKED OUT OF A PARKING SPOT AND MADE CONTACT WITH SOMETHING WHICH I COULD NOT SEE FROM MY REAR VIEW OR SIDE VIEW MIRRORS. LATER, WHEN THE EMERGENCY WORKERS WERE LOADING ME INTO THE AMBULANCE, I WOULD SEE THAT THE OBJECT WAS A LOW, CEMENT POLE, WHICH PROTECTED A FIRE HYDRANT DIRECTLY BEHIND THE PARKING SPOT I PULLED OUT OF. AS I PUT THE VEHICLE IN GEAR (DRIVE) WITH MY FOOT ON THE BRAKE, TO PULL AWAY FROM WHATEVER I BACKED IN TO, THE ENGINE REVVED AND THE VEHICLE ACCELERATED ON ITS OWN. THE VEHICLE LURCHED FORWARD (THE BEST WAY TO DESCRIBE IT IS THE WAY A PINBALL BOUNCES OFF OF A BUMPER ON A PINBALL MACHINE) AND CONTINUED MOVING FORWARD, EVEN THOUGH MY FOOT WAS STILL ON THE BRAKE PEDAL. THE VEHICLE DROVE FORWARD INTO THE PARKING SPOT I HAD STARTED FROM, OVER A CURB AT THE FRONT OF THE PARKING SPOT, THROUGH A PATCH OF LOW LYING PLANTS AND OVER A WALL WHICH IS APPROXIMATELY FOUR TO FIVE FEET IN HEIGHT. MY VEHICLE WAS AIRBORNE AND CAME TO REST IN THE LOWER LEVEL PARKING LOT, STRIKING A PARKED VEHICLE. IT WAS ONLY THEN THAT THE VEHICLE STOPPED ITS FORWARD MOTION.

I WAS ADVISED THAT A CLAIMS INVESTIGATOR WAS SENT TO THE INSURANCE-COMPANY-AUTHORIZED COLLISION SHOP TO
