Speaking for myself, I don't rely on other people to see me when I ride. I don't rely on other people to see me when I'm driving the cage, and I didn't rely on other people to see me when I drove commercially.... Hell, on Monday TWO people almost hit my pickup in the span of about 45 minutes. One of them pulled out of a side street and almost T-boned me. Classic case of someone looking in your direction, not "seeing" you and pulling out. Since I always try to keep an "out" around me when I'm on the road, and I'd somewhat anticipated that dipshit's move, I got out of the way before the twit could dent my door. The other was on the wrong side of the road in a fairly blind curve in a residential area.
All the same I don't see the reason to up the ante any by going out on the road on the bike when it's wet and dark. Goes beyond my personal comfort level and the risk vs reward ratio goes waaaay down.
