Sure, mastering the basic controls should be the first step, before ceding control to augmented systems.
However, I have yet to see a mirror that will see behind the back bumper: this has already prevented a host of dangerous situations for me ("person was there, then went somewhere, where the heck are they, oh: for some reason admiring my back bumper and the pretty light that the reverse lights give out").
If "I have a lifetime of experience with this so thats how it should stay" was humanities criteria for accepting new technology we'd still be bashing the neighboring tribes heads in with rocks tied to sticks.
A mirror I have a lifetime experience worth of knowing what is, no perceivable extra layer of processing required. A camera, not quite so, although of course it's a nice enough extra to have.
