Tip; pay attention to what you see in your rear view mirror in relation to the new wider positioning of the side views. You should be able to see the emblem in the middle of a car (or whatever reference point catches your eye right away) coming up on you either left or right side AND be able to see at least a 3rd of the car or trucks front on that side as they transition from being behind you enough so you can only seen them in the rear view and into being able to see them in your side view. I think of it as a hand off from one mirror, the rear, being responsible for seeing them and handing it to that sides mirror but only when both can see at least some of the car or truck at the same time. That's when I know the mirrors are good, when it's close to a seamless view.
When you get used to it, you WILL be seeing much more than before. What most of us do now is seeing a blind spot, right along side of us, nothing can fit in anyway except maybe a bicycle or a person. So, as someone said, always looking is always good, too.
