This was unintentional acceleration case: When I got into the parking space, the car was almost stopped and I was about to press the park button (gear) and the car suddenly accelerated and in a fraction of a second, climbed the curb, crashed into the fence, broke the fence and crushed on a tree. I was still applying brake to stop it and I could not do anything else. The following facts show that the acceleration was totally out of my control. 1.vehicle climbed the curb 2. and climbed the dirt part, shrubs 3. to hit the fence and broke it; It looked like something mall functioned. As a matter of fact, no safety feature worked and no sound signals went on ! Even vehicle's collision system did not kick in when car was climbing over the curb. Fortunately, I could get out of that car and my body was aching due to the seat belt and airbag explosion. (Driver side bag exploded for sure. I do not remember if the other side bag exploded.)
