You have to call 'em as you seem 'em. It's your neck out there.

My situation is very different. I don't use a lot of bike lanes and such, but I don't really need them either.

I'm not sure how I'd handle those high-speed two-lane rural highways. It's not in my experience handbook.

Is it possible to avoid oncoming passers by going off-road for a moment, until they pass? Does "super-lighting" seem like an option? What about rigging an independent, high-power yellow strobe on the front, and switch it on when someone's headed your way? Give them something more to think about.
