I've wondered for years why it isn't obvious to every last cyclist that wearing black, especially in spring and fall when it gets dark early, is a really good way to increase your chances of getting hit by a car. Nobody in the group of generally 50ish longtime traditionalist riders I hang out with pays any attention, and they laugh at my green/yellow/pink/anything BRIGHT shirts and jackets.
About dusk today, two of them riding together on a two-lane road through overhanging trees were hit by an SUV. No serious injuries, but they both fell. They're making the usual cyclist noises about rude drivers and sharing the road, but I've ridden with both of them for years, and warned them that they're just about invisible. I'm happy they're OK, of course, but I still don't get the fascination with black.
