On February 26, 2025 at about 3 - 3:30 p.m. I was turning into a parking space in a parking lot. I stopped my car just outside of the parking space and was turning left into the space. I lightly pressed the accelerator, as I have done hundreds of thousands of times since I started driving 57 years ago. The car accelerated, leaping forward and revving so fast that the car drove over a concrete divide (about 5 inches above the ground and 2 feet wide), flattened a sign, and landed on two cars that were parked on the other side of the divide. It was daylight and sunny. There were no obstructions.
