We use lights, reflectors, and wear helmets to protect us, because we have learned from experience that these keep us much safer. When I was considerably younger, I rode without these trappings. Few people used such safety devices in the mid 80's, however. I'm sure that If I had been hit at that time, there would have been a segment of the population that would have laughed, "Natural selection, stupid bicyclist!"
It disturbs me that others border on celebration of others' deaths. My own demise has been gleefuly expected in this forum, because I once hinted that I don't always come to a complete stop at stop signs.
Are the natural selectionists finding equal delight in preventable deaths from toddlers' unwise access to tubs and pools? Or adult's poor diet, travel to less safe countries, millitary service, smoking, and mental illness?
