My car doesn't have any cameras... But I've driven vehicles that do and I don't think they're part of the problem at all.
Just the other day I was trying to back out of a shopping center with a tiny parking lot right next to a brick wall while it was pouring rain.. Windows all fogged up and I couldn't see a thing, I sure wouldn't mind 1 of those cameras in situations like that.
Besides, how the heck could they be a problem if you're able to see live video of yourself backing into a wall? Anyone who can't pay attention to that probably doesn't care too much about their car.
