Interesting that you guys call them backup cameras - makes it sound like it’s a redundant camera to be used when one fails - as we call them reversing cameras here in Aus.

I’ve always been one to use my mirrors when reversing and saw no need for the reversing camera but then I bought a new car and it definitely does help in certain situations. More than anything, it’ll help me detect a child behind the car better if that ever happens. I still mostly use my mirrors but it’s handy to have the video there to refer to if needed.
