The last tow truck I took a ride on (modern, tilt tray, full lifts, etc) was operated by the driver who happily and easily juggled two phones ... he had one in a cradle, the other hand held, used the cradle one to look up routes, bid for jobs, and general map operations.
At lights or when refueling he was talking on the free phone while cross referencing via text and map searches on the cradle phone.
Additionally the truck console had screens for reversing, etc.
Point being .. we live in a world where it reasonable to have physical control, screen free, relative "dumb" vehicle that still has a diagnostics bus and rear cameras and distance sensors that can accessed via the drivers phone or tablet.
With cable | wifi and auth or some kind the operators smart device can upload music to the cars sound system and the vehicle can return infomation and visuals from sensors .. perhaps.
People who complain about screens are usually not complaining about that but rather about common functionality that used to be a single physical button now is buried deep inside a buggy menu system.
Car screens and I don't get on. At all. For backing up, what works for me is a full check first and directly viewing while backing up, augmenting with mirrors.
Eyes-on is me being as safe as I can possibly be.
The Full-Check part is what prevents that.
I also back-in to park. Pulling out compounds the safety.
You _can_ do it without a camera, but the camera saves a ton of time.
I back into spaces almost exclusively. reason: I see that I can do it when I arrive, and realize that exiting forward will be a breeze regardless of the future conditions (you are backing into an empty space, and forwarding into a space with other moving cars that are out of your control).
it's one forward lap and one backward lap, same difference, in addition to which I find steerability/maneuverability is much better with the "steering" wheels in the back, because after you get the forward aligned to enter the slot, you can simply steer away after that.
>90% of the people who back in take much longer to back-in than they'd take to back-out because it takes them more time to back up with any accuracy.
Head-in to the spot is just as fast as head-out into the lane because most people don't have any trouble going forward.
The result is that back-in is a net time loss.
Reducing the chance of a car accident by like 5% would be incredibly beneficial to everyone.
Safety. Several organizations that have automotive fleets recommend it for that. Pulling in backwards is safer because everybody can see everybody while that is occurring. Pulling out forwards is safer because you have much wider field of view and you have to do less maneuvering.
Liability. If you are pulling out forward and someone doing 50 in the parking lot hits you, you have a much better chance of them being at fault. If you get hit backing up, it is almost always considered your fault irrespective of how stupid the other driver is being.
