I'm beginning to wonder if the factory-installed reflectors on bikes do more harm than good.
"Oh, I have reflectors, so cars should be able to see me"
and
"Cars have headlights so they can see me"
and
"I don't want to add any crap to my bike"
and
"It's just a little battery powered flashlight, how much good can it possibly do?"
I definitely believed those things during my years of youthful biking indiscretion.
