While pulling into a parking spot and coming to a halt, I put the car into park mode. My foot was still on the brake. Instantly the engine went into "overdrive" and lurched forward over a parking curb and through heavy brush and finally came to a stop after hitting a pine tree. The engine was still screaming and the tires still spinning until I hit the off button. I had my foot on the brake the entire time to no avail. The heavy brush slowed the car somewhat. The airbags didn't deploy. I had several witnesses and they all stated they saw my brake lights on. I plowed approx. 50 feet through the brush before hitting the tree. I was the only one involved and was not hurt. This was Thurs. Sept. 28, 2023. It was in a state park and no police report made. Park Ranger took down info.
