The sad thing is no matter how visible you are, you just need one stupid drunk driver or someone on a cell phone to hit you anyway. I ride in the dark everynight so I have a rear blinkie, lot of reflective tape on my rear trunk and everywhere else on the bike and two headligh but I'm still a bit scared every time I hear a car coming up behind me. The good thing is that we are as likely to die in our cars than on our bikes so why stop riding!?!
