Systems and methods for preventing a motor vehicle side door from coming into contact with an obstacle are provided. One system includes an outside rear view mirror, a camera coupled to the outside rear view mirror, and a controller coupled to the camera. The camera is configured to detect the obstacle and determine the distance between the side door and the obstacle, and the controller is configured to disable the side door if the obstacle is within a threshold distance of the side door. Another system replaces the camera with an ultrasonic sensor to detect the obstacle and determine the distance between the side door and the obstacle. A method includes determining the distance between a plurality of motor vehicle side doors and the obstacle, and automatically disabling each motor vehicle side door that is within a threshold distance of the obstacle.
