I WAS PARKING MY CAR IN FRONT OF A STORE. CAR WAS IN PARKING SPOT, READY TO STOP. ALL OF A SUDDEN, CAR ACCELERATED, JUMPED THE CURB, WENT THRU SIDEWALK INTO THE STORE AHEAD. LUCKILY, STORE WAS VACANT. CAR KEPT GOING THRU THE STORE, CAME OUT FROM THE BACK WALL ONTO THE RAIL GUARDS WHICH FINALLY STOPPED CAR. CAR WAS DAMAGED.
