If you position your mirrors right, you'll never have a blind spot. I found that it took me awhile to find the right position, because I actually point the side mirrors far out to the sides. Took me awhile to get used to it, but now I can see a car pan from my left mirror, to the center, to the right perfectly. Took me awhile to train myself, but I'm now confident with it and I knopw if I can't see it in my mirror, I'm not going to hit it when I change lanes. Simple enough.
