Your driving school instructor is correct. When I took Driver's Ed, the common practice was to align them as you do, so you can just see the side of your vehicle in the mirror, for reference. I am going to guess that sometime in the 1990s somebody did a study which showed that was not the best way, that it lead to much larger blind spots. I say 1990s as that is when I first started hearing about setting them the way your instructor told you.

I have to admit, I was skeptical at first, and it took some getting used to, but with my mirrors properly adjusted, I can see the front of most cars in my side mirror while the back of that car is still visible in my rear mirror. You might be able to get a Smart Car in my blind spot, but that would be about it.

You will be much better off to learn how to do it right from the start so you don't have to unlearn bad habits.
