If anyone from Ford is reading, PLEASE LISTEN!:
I've used cameras on many vehicles, and while they give you great visibility behind the vehicle, it creates a DANGEROUS distraction. How so? When one is looking at the camera, one CAN NOT simultaneously watch either side of the vehicle for traffic approaching (like in a parking lot). People become too reliant on the camera. IMHO what works tremendously better are the radar systems. Yes, one will not have better rear visibility, but it will allow the drive to use his eyes AND his ears to prevent hitting an object.
I have kids and understand the concern about being able to see behind me. The camera however does not let me see all of the back of my vehicle where a child could be standing, where as radar will detect something.
