I was driving slowly up an aisle in a parking lot and spotted a shady place on my left just next to a car already parked. I moved in slowly at 90degree angle to set the car into the parking space with my foot already on the brake. I pressed down the brake further as the car was about to be at the right place. Suddenly, the car accelerated at what seemed full throttle into a brick retaining wall 9-10 feet in front of me. The car backed down in the parking space where it immobilized.
