My wife was pulling into a parking spot at a Safeway in Seattle. The car, instead of stopping, sped up when she stepped on the brakes, slamming into a brick wall. She shifted into reverse, and the car sped backwards, then shifted to drive, and sped forward and slammed into a wall again. She shifted to park and pulled on the parking brake. Then, after 5 minutes with the car off, she drove home without incident and parked, although the car was severely damaged.
