I don’t think you were jamming on the brakes while parking. I really think your situation was the same as mine. Pulling lowly into the parking space on with foot mistakenly over accelerator. I lightly pressed on the pedal to stop the car. However, since it was the accelerator the car lurched forward. Thinking I was pressing the brake I pushed harder which caused full acceleration. I hit and bounced over the concrete parking barrier and ended up in a ditch beyond the parking barrier. At the time I swore up and down that it my foot was on the brake, but in reality it was over the accelerator. If they ever provide the log information to you, I think you will find the same thing. For me it was a $4000 lesson, but now I am absolutely sure of my foot position every time I park.
