I WAS SLOWLY MAKING A LEFT TURN INTO AND PULLING INTO A FRONT END IN PARKING SPACE WITH MY FOOT ON THE BRAKE, THE CAR AS ALREADY GOING STRAIGHT INTO THE PARKING SPACE WHEN THE CAR SUDDENLY ACCELERATED, COULD NOT BE SLOWED DOWN OR STOPPED BY THE BRAKE, JUMPED THE CURB, AND CRASHED INTO THE BUILDING. AIR BAG DID NOT DEPLOY.
