Coupla' thoughts.

I've used the CycleAware, helmet mounted, for years, mostly because I don't like wearing glasses when riding. SW FL is pretty warm 9 months of the year and sweat dripping on glasses can be blinding. Years ago I tried a bar mouted mirror and finally just took it off....vibration made it totally useless, plus the VERY narrow field of vision doesn't do much (the closer your eye is to a mirror the greater the field becomes.

Two thoughts for those having problems with them. Determine your "Shooters eye" and mount/use the mirror on that side. While your left side is most critical riding, most of us are "right eyed".

If you are just too uncomfortable not covering your left side as primary, use the mirror on the left but learn to "long blink" with your right eye. Your left eye will then be primary and will focus well behind you. A very slight head turn allows you to cover at least three or four riders wide behind you in a tight peleton. The "blink" should be so quick that you are not riding "one eyed" for more than one second. You can't use both eyes to look into the mirror...ever!

I have to agree with aggressive riding concerning cars behind. I rode mostly in Cape Coral FL and on a typical 40 mile ride, I'd only have a mile or two that were not on 4 lane divided blvds with very light traffic. After experiencing a couple cars passing me "straddeling" the lanes, I started moving to the center of the right lane when I'd see a car coming up on me. I found then that all drivers would fully change lanes and pass me comfortably. I know, that's not an option for most of you.
