I was backing out af a parking spot, and backed into a car parked behind me. I wasn't going that fast, like 2 and a half or so. But the people that owned it before me had hit the car in the same place, so the bumper there was already a little weak. Also, it was really cold that day, like aroud 10 degrees, so the bumper was really brittle. So when I hit the other car, it just cracked.
