I WAS BACKING UP AND CHANGED MY GEARS INTO DRIVE, TURN THE STEERING WHEEL AND FOOT STILL ON THE BRAKE, CAR JUST JERKED AND TOOK OFF AND I ENDED UP HITTING SOMEBODY'S VAN. WHEN I TRIED TO HIT THE BRAKE ALL THE CAR DID WAS SPED UP SO RIGHT BEFORE I WENT OUT IN THE DRIVEWAY UNCONTROLLABLY, I HAD TO PULL UP THE PARK BRAKE JUST TO STOP
