I don’t have that problem at all in my car.
I live on a one-lane road, and the turnaround in my driveway turns into foot-deep mud when it rains, so I back into my driveway. …About 300 yards of backing up, all in, with some fairly sharp turns and a steep drop on one side of my driveway. It’s really simple, as long as there’s any light; at night, the reverse lights aren’t really bright enough to see what I’m doing. BUT my display is about 8" wide; I’ve driven trucks and vans where it’s a 2" wide section on the rear view mirror, and those are a pain in the ass.
