I WAS DRIVING ON THE PARKWAY AT ~40 MPH AND ATTEMPTED TO SLOW DOWN BY STEPPING ON THE BRAKE. THE CAR DID NOT SLOW DOWN BUT ACCELERATED. AND STRUCK THE CAR IN FRONT OF ME. EVERY TIME I PRESSED ON THE BRAKE, THE CAR ACCELERATED SO THAT THE CAR STRUCK THE CAR IN FRONT TWICE. I TRIED TO TURN OFF THE IGNITION AND WAS UNABLE TO. FINALLY, I PUSHED HARD ON THE BRAKE ENOUGH TO SLOW IT DOWN AND I WAS TEN ABLE TO PUT THE CAR IN NEUTRAL. THE ENGINE RACED BUT I WAS THEN ABLE TO TURN IT OFF. DESPITE DAMAGE TO THE FRONT OF THE VEHICLE, THE AIRBAGS DID NOT DEPLOY. *TR
