What we've learned on the track

I would add that the setup for the RVM should be done with your head at the angle (or no angle if you choose to move your eyes only) that you will be positioned when using the RVM. The same would be true for the pax and driver's side mirrors.

If you wear sunglasses, pick one set and make your adjustments with your choice of sunglasses properly seated on your head. Same with vision-adjusting glasses.

Since most people wear sunglasses (or should), picking the right pair for driving should be the first consideration. Not boating or aviation, a second set for these specific activities (different colors, reading adjustment glasses, etc).

Not only more quickly, but with practice, more accurately. Like an outfielder chasing down a fly ball, head still = locked in vision. Head movement disrupts the eye causing the inevitable momentary blurring. The momentum of the head forces the eye to move even ever so slightly in the socket.
