Here is my back up camera on my ride. Many of us have them. Mine doesn't work. lol The lines don't really help me, I'm not going to lie. I was trying to back up into a parking spot at a restaurant the other day as you can see here and I still did not land between the lines. 

Either this feature is wasted on me, or I'm just really bad at parking. I think I get too concerned with watching the green lines and lose track of what I'm doing. Does anyone else not get much help from their back up camera?
