## Narrative
While parallel parking in a parking structure;   my car accelerated full throttle backing up hitting the back wall ;  then I tried going forward to straighten the car up,  it accelerated full throttle forward hitting the front wall.   I had an doctors appt.  there and decided to still straighten car and I said if it goes full throttle again I would immediately put the car in neutral and turn the car off,  which I did. Each time the car went full throttle I hit the brake pedal as hard as I can push. Leaving the car I tried locking the car with my key fob,   it wouldn't lock or turn off the headlights,  it caused the horn to keep beeping for no reason.
