That said, I'd much rather have a backup display in my rear-view mirror than a giant touch screen
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.
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.'
By your logic we could also hand everybody heroin and an assault rifle and abolish most laws, people watch TV after all and therefore can be taught not to do bad things.
In addition, the existence of kids who are capable of naming themselves must mean that other kids should be bumper mush. This is the only way to preserve the American Way.
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.
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.
My hatchback has about the best you could get (and they don't sell it here anymore) and I still added a backup camera, it's very useful.
My little GTI with a backup camera made me an invincible parking machine.
It also enables auto-parking and other enhancements while not inhibiting anyone that wants to perform those functions manually.
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.
I've caught myself just backing up without thinking about it in the car with the backup camera. never done that in the old-school mirrors car.
I don't know if there are any studies that back up backup cameras.
I sure would be pissed if I had a car with a backup camera and something like this bricked the big center screen in my car, however.
