Idiots, it happened to me something similar. I was reversing out of my park lot, an old woman was coming and what did she do? she continued to go, without stopping and waiting for me to go out. so pressed the horn and I stopped. She came out of the car saying I hit her and I had to go out and see the damage BLA BLA BLA... in my bumper there was a nail of white paint, but her car was perfect. Of course she said I hit her and there was a little scratch
