Not paying attention. Oh well, I guess that just points out the limitations of that style of bike mirror.
Yeah, I made sure I was specific about that. I used a head mounted mirror years ago. Then when I started cycling again, I just could not get that type to work well for me. Aging eyes changed where I could look with clarity and comfort. Aging eyes also made looking over my shoulder less effective as well, and progressive lenses distort peripheral vision. Not to complain about aging, I never want to stop, but a mirror is a nice convenience. Certainly not a danger, unless you happen to impale yourself by crashing on it.
