Regarding mirrors and skill vs backup cameras. My son worked as a lot boy washing vehicles in high school years. One time he had a Class A motorhome in the wash bay, and after he was through detailing it he walked around to make sure all was clear and then backed up (using mirrors only). Meanwhile a mechanic pulled up behind him and parked a brand new GEO off the transport truck. Backing up the class A my son basically squished the GEO. Personally I am all for most new helpful safety features and that includes backup cameras. Last year saw a little girl saved by automatic (and dramatic) braking when she rode her bicycle right out in front of car going through a parking lot with the driver completely looking in the opposite direction that the girl came from.
