I have never figured out how I would get any value out of a rear camera.
As a replacement for the rear view mirrors, if that is even legal, how do you pan it? For my mirrors, I can lean forward to see more of the adjacent lane. I'm pretty sure that would not work with a camera system. With both hands on the wheel, how do you solve that problem?
fwiw, I can see a Miata following me at a distance somewhat closer than 200 feet. I want to be able to keep an eye on my daughter when she is driving behind me. I am not looking for the tailgater.
I can see the value if it would allow me to pull into a campsite in the rain and get it just as close to the tree as I would if I were to get out and look. Avoiding getting out to look would keep me dry. But the quantity of cameras that I would need to install would be high. I need to see behind both wheels, behind the plumbing, behind the rear bumper, watch the overhead limbs, and still see the trees on both corners. I never camp in a paved site. It is, at best, graded dirt in a forest service campground. The previous occupant may have left rocks where I might not see them while backing.
Having said all that, when towing a car behind a motorhome, I can see a lot of value for that.
