One time when I had just recently gotten my driver's license, I was driving in the parking lot of a pizza place, and had a slight accident. I drove into a parking space like usual, not really looking at what was on the ground. Everything was fine till then, and I went in to get the pizzas. When I came out, I saw the car across from me was gone, so I figured it would be nice and easy to just drive straight out. Unfortunately, what I had failed to see earlier was the concrete blocks between the spaces. I was just horrified as I feel this massive jolt underneath the car, and realize my error. Having to choose between backing back over it, or just following through with it, I chose to just drive straight on through and drive away, hoping nobody had noticed. There were never any problems with the car, so hopefully it didn't do too much damage.
