At stores I always park as far away as possible to avoid dings. But be careful if its down hill in the parking lot. Yesterday I parked at a store, I did notice it was downhill, but looked around for carts and did not see any. So I went in anyway. When I came back I was sitting in the drivers seat on my phone for a few minutes with my window down. I heard a cart start rolling. Looked out and it was headed right for me. Jumped out and stopped it inches from my car. By that time it picked up some good speed.
