Sorry I meant to say their mirrors - but rear view cams do not give much in the way of peripheral vision (yes, I have modern cars too). I've regularly had dumb people cross right into my rearward path even though I'm currently backing up, have the white lights on, etc.

What I meant was: people backing up just using their side/rear mirrors are scary. They don't have good spatial awareness of what's around them. A rear-view cam for them adds a whole lot of safety though.
