I was sitting in park in line at a gas station waiting to get gas. when the person in front of me left, i moved my car from park into drive, the car went into unintended, unexpected, high power accelerations, holding down the brake pedal did little to stop the car was going full bore. i ended up hitting the gas pump barrier to avoid hitting other vehicles that were leaving the gas station. i was thankful i didn't kill anyone or set the gas station on fire.
