I got into an accident because my back up crap camera did not warn me that a car had turned behind me. Also when and backing up and a car is coming it doesn-€™t indicate the car is coming until it-€™s behind me. I-€™ve taken it to the dealer and they say there-€™s nothing wrong with it. Also there is no break when you come too close to something in front of you.
