I was pulling into a parking space when the gas pedal went to the floor causing the car to accelerate uncontrollably. I put my foot on the brakes pushing them as hard as I could with the car not slowing down at all. It caused me to wreck my car into a building totaling my car and giving me a head injury that required me to go to the hospital. There was no floor mat. It went to floor all on its own and would not stop accelerating. This needs to be investigated.
