Because of the angle of the stem upon which my Garmin is mounted, the glare is so bad I can't easily see any of the data displayed, so I almost never look.
I know, when I get home, I can download it onto my computer and see all the data (and more!) from the comfort of my desk chair.
So, without really wanting to, my Garmin has made me a safer cyclist! Funny how that works.
