I ride a lot of country lanes here in Dorset. Some are Sustrans/National Cycle Routes. The width of the road is not possible for 2 cars to pass at the same time, however, some cars that approach me do not treat me the same they would a car, and continue at speed towards me expecting me to stay tight to the kerb or move closer onto the kerb
I have noticed recently that if I position myself another foot or so closer to the middle of the road, rather than my usual 1-2 feet from the kerb, as they approach, they are forced to slow down and give way. If they don't slow down as they approach me I move back close to the kern again. A wave to acknowledge them for slowing down/pulling in is always given on my part. I do this when the road ahead is clear and visible to all, blind corners I still hug the kerb just in case.
I'm also beginning to think that perhaps major roads are potentially safer than these narrow country lanes that Sustrans/National Cycles routes encourage cyclists to use...
