I think backup cameras have surpassed the mirrors in a lot of cases. I'm just surprised it hasn't progressed faster and further. Why every car doesn't have the option of an around-view top-down backup system is puzzling.
I find the kids (n=3) make more steering mistakes and see less when looking forward at the screen compared to turning around.
I think the physical action of tuning is a somatic trigger that the steering is different and to swivel the head around for hazards.
In driver's ed we were taught to put our right hand behind the passenger seat whenever looking back to go in reverse. As if to reinforce the modal/perspective change.
I notice the kids don’t see hazards (pedestrians) as well on the car with a backup camera as they do in the car that requires you to physically turn around.
The original backup camera was on the Prius because it had a huge blind spot, this fix should have been to th blind spot, not the degraded function of a fisheye lense and a driver facing forward.
