I don't understand how cyclists feel safe on the road. I would never cycle on the road...  I play a strong defense, in the most kind and polite way possible.  My backpack is bright (like, primary color) red, and has two big reflective stripes on the back.  I generally have a bluetooth speaker blaring, sort of my own variation on "loud pipes save lives".  My front-facing light is a flashing 930 lumen CREE LED, my rear-facing light is a flashing red LED strip.  Both are visible from easily 50 feet away.  To top it off, I have strips of industrial reflective tape (the kind they use on emergency vehicles) on all the parts of my frame, and my helmet.  You get a light anywhere near me, and I glow.  I use hand signals.
