## Narrative
Well backing out of a parking space at the grocery store. My rear camera failed to activate even after several times trying to get the camera to work. I decided to try and back out by just looking over my shoulder, but could not see through the back window and collided into a shopping cart. None of the advanced systems activated no object detection, no camera and no collision warning.
