No, it's not you.
I find that I have to continually duck or lean in order to see what I'm looking for in the mirrors.
I try to set the mirror angle at a mid-way point between seeing cars just behind me to those farther away. It's tricky to do this as moving the mirrors while at a standstill doesn't give the correct perception and moving them while moving allows better judgement on the correct angle but is a bit dangerous, especially when moving the right mirror.
I had them set just right a while back but they moved slightly after clipping a few cager mirrors with my own in heavy traffic.
