This is an article about motorcycling but first let me ask a question about driving a car.
Motorcyclists, when you are driving a car, do you check out the rear window when backing up, or do you just look at the dashboard rear-vision camera?
Be honest.
I ask this because I have noticed myself developing a new bad habit. Rather than twist my neck and body to look out past the headrests, and through the tinted rear window, I have begun relying on the car's back-up camera.
Oh, I make a guilty half-glance toward the back before going into reverse; but I can't pretend that's adequate.
This new bad habit is going to be a hard one to break. I know, because I have a different bad habit when motorcycling that I can't seem to break.
Here it is: When I give one of my rear-view mirrors a routine check while riding, I automatically then immediately shift my vision to check the other rear-view mirror.
Doesn't sound so bad, right?
But consider this: I realize that I am not checking the view forward between glances in the mirrors.
Looking where you are going is generally going to be more important than looking at what may or may not be catching up to you.
I've never seen this addressed in any safety lecture or material.
I suppose I ought to be looking forward immediately after looking anywhere else.
Even if I am looking in one mirror while considering shifting lanes (I'll have to turn my head then, too) it is unlikely that I would be thinking of changing lanes both left and right. It's one or the other. So why do I look at both?
The additional effort in pausing to look forward is minute. It would call for me to refocus my eyeballs from the very close mirrors to look far up the road. Is that asking too much?
Seemingly so. I can't seem to break this habit, although I try.
In context, relying heavily on the automobile back-up camera for backing is somewhat justified. The camera is very good.
It's apparent that auto manufacturers have sacrificed the view out the back window to styling, streamlining, comfier seatbacks and window tinting.
Besides, they know we are too lazy to twist around.
Motorcycling, at least on a vintage motorcycle, still requires plain old eyeballs.

"I've found one Honda catalogue from 1965 that shows mirrors. From the mid '70s all of them do.
The next instances of rear view mirrors in the Harley museum come on bikes prepared for the military in World War II and on police motorcycles of the 1950s. In these cases, I suspect the authorities drawing up the bid specifications required that mirrors be included.
It's my belief that some vintage motorcycles did have mirrors, but these rarely show up in advertisements of the time because they cost extra, were strictly an after market accessory or were considered too ugly to display. Jorge pointed out that even today, 2009 Royal Enfield models are shown on the 
Good rear view mirrors are important safety equipment, but the overgrown appendages Royal Enfields come with instantly mar the looks and mark the motorcycle as not nearly as vintage as the rest of its appearance suggests.
