On Saturday, 3/4/2023, I stopped at a supercharger lot to charge my car during a trip. As I entered the lot, I noticed that the road conditions were poor, almost like a gravel road. To be cautious, I drove slowly towards the three empty parking spaces in the middle of the lot, intending to park in the middle spot. I noticed that the road conditions were even worse in front of the parking spot, but it looked wide and not too deep, so I didn't think it warranted serious concern. I carefully maneuvered the car around to prepare for backing up. I've been using the HOLD braking mode, which allows for one-pedal driving, for more than five months. Just as I lifted my foot off the accelerator, the car jerked forward from a small pothole. I still expected the car to come to a stop, as my foot wasn't touching the pedal. I made a comment to my passenger that I was puzzled why the car was still moving as I looked down at my foot far above the pedals. Suddenly, there was a really loud sound (like revving if I remember correctly) that I had never heard before, which surprised both me and my passenger. We exchanged a puzzled look just as the car suddenly jumped forward at full power and hit the car in front of us before I could do anything to stop it. I believe that this was a software issue related to overcompensation of losing traction control on both sides as the car came to a stop. It's important to note that I did not purchase Tesla's Full Self Driving and was not using any driving as
