WAS MOVING VERY SLOWLY - IN A PARKING GARAGE. BEGAN PULLING INTO A SPACE AND APPLIED BRAKES. ENGINE REVVED (THROTTLE OPENED?) AND ACCELERATED BY ITSELF A FEW FEET IN TO A WALL. GIVEN THAT IT WAS ONLY A FEW FEET AND A LARGE CEMENT WALL, NO MAJOR DAMAGE. MY FOOT WAS FIRMLY ON THE BRAKE, THE BRAKES WERE SQUEALING AND THERE WERE WITNESSES AND PROBABLY VIDEO GIVEN THAT IT IS A PARKING GARAGE. BURNING BRAKE SMELL ALSO VERY APPARENT. I WORK IN INSURANCE AND KNOW OF THIS SORT OF CLAIM. I DID NOT MOVE MY FOOT, OPENED THE DOOR AND LOOKED, FOOT FIRMLY ON THE BRAKE. FLOOR MAT WAS NOT A FACTOR. *TR
