I WAS AT A GAS STATION. I FORGOT TO PUT THE CAR INTO "PARK". HOWEVER, I WAS ABLE TO TAKE OUT THE KEY AND LOCK THE DOOR. I HAD MY BACK TO THE CAR WHEN I WAS PUTTING MY CREDIT CARD INTO THE PUMP. I HEARD SCREAMS AS PEOPLE RAN OUT OF THE MARKET AND YELLED THAT THE CAR WAS MOVING DOWN A HILL. AS I TURNED I SAW MY CAR CRASH INTO A PARKED TRAILER (18 WHEEL TYPE.) ALTHOUGH THERE WAS A LOT OF DAMAGE TO MY FRONT END AND I BENT THE STEEL STEP ON THE CAB NO ONE WAS HURT. MY DOG MERELY FLEW INTO THE WELL OF THE CAR. I HAVE HAD MANY FRIENDS CHECK THEIR CARS AND NO ONE WAS ABLE TO TAKE OUT THE KEY UNLESS THE CAR WAS IN PARK. HOWEVER, THESE CARS WERE NOT A FORD EDGE. SINCE THE ACCIDENT I HAVE TESTED MY CAR MANY TIMES AND I CAN ALWAYS PULL THE KEY OUT. AS YOU KNOW WHEN A CAR IS IN DRIVE IT ACTS LIKE ITS IN NEUTRAL AND CAN REACT TO INERTIA. AT THE TIME I WOULD NOT HAVE NOTICED THAT THE CAR WAS ON A SLANTED DRIVEWAY. A CHILD IN MY CAR COULD HAVE HAD A SERIOUS INJURY. SOMEONE NOT PAYING ATTENTION COULD HAVE BEEN HIT BY MY CAR. I CHECKED WITH MY DEALER AND WAS TOLD THAT THERE ARE NO RECALLS ON THE FORD EDGE ABOUT MY SAFETY ISSUE. LOCAL DEALER NOT INTERESTED IN HELPING AND I CAN NOT REACH A LIVE PERSON AT THE FORD'S WORLD HEADQUARTERS. THERE IS NO PROMPT FOR A SAFETY CONCERN.. AS OF NOW I AM RESPONSIBLE FOR THE DAMGES TO MY CAR AND TO THE CAB. LEFT FRONT BUMPER AND LIGHT DAMAGED.
