AT 2:30 PM ON OCTOBER 30TH 2015 I PARKED IN A COMMERCIAL LOT. I LEFT THE VEHICLE TO GO INTO A STORE, WHEN I CAME OUT OF THE STORE I REALIZED THE CAR WAS "RUNNING". I OPENED THE DOOR AND REACHED AROUND THE STEERING WHEEL TO TURN THE CAR OFF BY PRESSING THE START/STOP BUTTON. I THINK PROCEEDED TO LEAVE THE VEHICLE TO GO TO ANOTHER STORE. WHEN I CAME OUT OF THE 2ND STORE I SAW MY CAR HAD ENGAGED INTO DRIVE AND MOVED OVER 50 FEET ACROSS THE PARTING LOT AND HIT ANOTHER VEHICLE. WHEN I GOT TO MY CAR I FOUND IT RUNNING AND IN "DRIVE". THIS ALL HAPPENED WITHOUT ANYONE IN THE CAR. THE CAR BASICALLY "RAN AWAY" WITHOUT ANYONE IN THE VEHICLE.
