I have one in my car, but it doesn’t come on right away! Although I try to cultivate the habit of waiting for it, this is largely a losing proposition. I suppose the newer ones will initialize faster, and I should think this would be a point of the law, as long as they’re making one.
Also, even in operation, it has its drawbacks. It is very hard, cognitively, to integrate the backward screen view with the natural visual scan. When I first had it, I narrowly avoided several disasters about to be caused by fascination with the screen. There is even a warning on the screen to look around, although I never understood what it meant until I had my close calls.
All in all, I’m not so sure it’s “The Answer”.
I’ve got one in my 2013 Honda and it comes on immediately.
The answer:
“But my backup screen said it was Ok to backup!”

My parents bought a new Honda with it as standard equipment, along with a right-side mirror camera.
Nifty, but what a distraction to ‘driving’...
Frankly, the first thing I’d do is hack the interface to turn it off & on at will. The big problem is that the ‘displays’ are integrated; you can’t disable the display without losing radio, gps & other functions.
