Being able to see EVERYTHING that's behind you is a distraction?
Too much info can always be a distraction.
Like these bozos driving around with their headlights on in broad daylight. A hundred cars on the road and every one of them screaming HEY! LOOK AT ME!!!!
Not a fan of DRLs in temperate latitudes, obviously.
Again; Being able to see EVERYTHING that's behind you is a distraction?
Uh, no.... but having too many stimuli telling you that can be. Ever heard of TMI?
Anyway, cameras give no depth perception.
I think we affix a lot of technology not because it does anything useful but just because we can.
