If you are serious about it, check in to Hi-Vis riding gear.
Yep, that helps. But even with all the lights in the world and high-viz gear, there's ONE thing much more effective than all of that combined: Pretend nobody can see you, and that everybody wants to kill you
. That's it. And if somebody cuts you off, you're not going to get mad, because you already have the proper frame of mind that everybody wants to kill you. So whoever don't succeed, you should be happy, instead of mad. I learned that lesson the hard way, so now I ride super defensively. Anybody that could pull in front of me, I slow down enough that I can stop if they do (or get covered by a car). Always watching my 6, obviously, but it's been well over a decade since that last accident. I also don't commute at all; only use the bike for trips to the twisties a few times a year... and on weekdays (no traffic in the mountains, so more fun). I'm fully conscious that in heavy traffic, no matter how defensive you ride you could still get T-boned, or run over a crate or something (I've seen washing machines and couches, folks
). Tons of ultra-stupid drivers with crappy (and uninsured) vehicles here, so I don't push the envelope. If I have to drive in heavy traffic, I take a car instead. Good luck.
