I know BMW turn signals are a meme (with good reason...), but I've noticed the exact same behavioral trend with Lexus drivers as well. It's really just those two makes in particular.
Great, another feature that will save dozens to hundreds of lives (disproportionately of young children) every year, while adding only a few bucks to the bill of materials for cars that already have a display screen.
I do wish parents would stop teaching kids to take the short route over the carpark on the way to school. They save a couple of meters but walk behind cars backing out of the car garages... The back camera is handy but you won't see them if they walk on your side of the lane, too close to the 90 degree edge of the car.
And to make it more fun, our car has an overlay on the left edge with a top down view of the sensors around the car. That one blocks the view completely in that edge. And has a black background window that slowly fades away.
I think parents who have lost their children to cars backing out of driveways while children are playing on the sidewalk would disagree with your description of 'unneeded'
It wouldn't be an issue if we went back to making cars small enough you could see out of them. Legally requiring a certain level of rear visibility would be a good thing (and, sure, in some cases a camera might be the best way to achieve that) - and throw in some pedestrian collision safety requirements while you're at it. Legally mandating the expensive gadget-based way of doing things seems horribly shortsighted.
You'll never come close to getting the visibility that you can with a backup camera. With a decent backup camera the only blind spots are actually underneath the car itself. You can't possibly match that without a camera on anything other than a motorcycle. Setting the legal requirement of visibility without mandating a camera would either make it completely impractical to avoid a camera or you'd be sacrificing visibility by making the mandate achievable with only mirrors and windows.

Your perspective is biased. If the backup camera had been invented before you were born and the automobile after you had been born than you would consider it only logical and familiar to see backup cameras on the wagons and horse drawn carts that you were used to but you would consider automobiles to be 'the expensive gadget-based way of doing things [that] seems horribly shortsighted.'
If backup cameras weren't expensive gadgets then I wouldn't consider them expensive gadgets, sure. But they are, so I do. When the facts change, I change my mind; what do you do?
Wouldn't the entire rear of the car and the rear seats have to be glass to exempt a car from having the camera?
A bigger rear window wouldn't have let me see the toddler who'd wandered a short distance off from his parents in a car park and was standing right behind my car.
Look at the split rear window on the Prius; it does exactly that. If the driver is tall and turning their neck, or short and using the center mirror, the sight-line from the driver's seat extends below the rear seats and down into what would ordinarily be the tailgate.
You can't see the pavement under the bumper, but you can see a kid on a tricycle right behind the car.
Personally I find rear view cameras to be quite disorienting. The view is quite distorted by the wide-angle lens and it's not clear where it can see and where it can't. Do I still have blind spots if I look at only the screen? Where are they? With a mirror I get an intuitive sense of what it can and can't see. Also, I expect the view to move when I move my head like in a mirror, which is part of what makes it so easy to get a sense of where the mirror can see. I suppose someday I'll get used to cameras, but today is not that day.
I used to pride myself on my ability to fit into small parking spaces and parallel park even big vans pretty precisely, and a backup camera blew all that out of the water because I can fit anywhere now.
My little GTI with a backup camera made me an invincible parking machine.
Also demanded by customers. A well implemented backup camera is much better than trying to use a small rear view mirror or twisting around to look out a small rear window. The backup camera can give you a wider field of view including low down where a small child might be. It is also much brighter in the dark than your eyes normally see.
This doesn’t mean that I am not also checking the surroundings but the backup camera is such a big improvement that I would not buy any car without one.
