Back-Up Camera Does Not Help Me

Can I say that this right here means nothing to me? lol I understand that the purpose of a fancy back up camera is to help me back it on up and the lines to what, help me back properly between the painted lines? Nope! No matter how hard I try, I just can't do it. lol 

I'm telling you, these fancy back-up camera's are lost on me. Am I the only one? I feel like I'm taking the driver's test all over again. lol
