I was in a parking lot at a near-complete stop. I needed to nose the car about 18 inches to move it all the way into the spot. I lightly touched the accelerator to inch the car forward, and it shot forward as if some outside force had stomped on the accelerator. The car jumped the sidewalk and slammed into the wall of the building. The car inner body bent and the car is totaled. The airbags did not inflate. The passenger in the passenger seat sustained a fractured sternum and two broken ribs from going into the seatbelt. The driver sustained a sore neck and dizziness.
