Do bikes still come with the reflective plastic plates that are wedged into the spokes? The advantage is that they rotate as you pedal and that makes them more visible. Mounted fore and aft, they show a driver what you are. But seems many people regarded them as dorky, and removed them. Better to be cool than dead, I guess.For night/dusk, it can't hurt to wear reflective colors. Reflective sidewalls are good too. Safe biking may seem sort of dorky as far as fashion, but better to be seen than viewed.
