I'd like to propose a little group project in the interests of safety and education.
Wear your usual commuting gear on your usual commuting bike. Go to a dark-ish bit of road at night. Have someone sit in a (parked) car, with the headlights on, and take a photo of you on the bike as you ride.
Exact position is your call. You choose whether to simulate a broadside, a rear-ender, a left-turn-head-on, a right-turn-cut-off, etc, and you decide what is a realistic distance. These aren't really "portraits" so no harm in not showing your smiling visage. Personally, my saggy butt in dripping rain pants is really my best side anyway.
Let's see how illuminated, blinky, reflective, brightly colored - in short, how visible - we really are!
Game? I'll take my picture this weekend and post it here. If it rains, all the better.
If you want to be all techie-showoff and embed a video, feel free.
(I'm also going to have my kids do this, so they can grasp how invisible a dark-clothed rider really is.)
