Many experts use their peripheral vision and look in their mirrors a dozen times a minute. Sometimes a lot more. And they do this without taking focus off of what’s ahead of them.
The goal is to build your ‘reading traffic’ skills to a level where you can safely look in your mirrors without it distracting you from what’s ahead.
Looking over your shoulder is also a viable way to see what’s going on behind you, but as you continue to increase skills with mirrors, you’ll notice that you get more information in a quicker amount of time with less effort, less distraction and less deceleration by using your mirrors properly on a regular basis.
