@Owlet64 ill pull over if there are more than 5 cars and the road is single track for more than a mile, and I can also see the ability to pull easily back out, when it is safe ie into a passing place. If there is a dashed white line or two distinct lanes and it’s just oncoming traffic then unless I’m feeling very charitable I probably won’t, because to be honest holding speed is quite easy but getting going back up to 18-20mph from standstill repeatedly is energy sapping. I definitely won’t stop on an uphill because if it’s steeper than about 6-8% then getting going again is particularly challenging and sometimes ends up meaning walking pushing your bike to the top of the hill. If people haven’t cycled, or only pootled a couple of miles with the kids they probably don’t get that it’s difficult to do.
certainly for me, and my friends, we are considerate and allow things through when we can, without making it unduly difficult for ourselves. We waved through anyone waiting behind us when we stopped at roundabouts/T junctions today. (We don’t really see that many traffic lights in the countryside, but have done this at temporary lights in the past as well) but we aren’t going to pull in to a side road if it would be a reasonably blind exit again and we are sitting at 20+ mph on the flat on a normal 2 lane road just because it’s been 30s and the car hasn’t overtaken yet for example. It’s not because we are inconsiderate, it’s acting within the reasonable limitations of our engines and machines which being entirely human powered are not the same limitations as a car engine.
Cyclists will know every local suitable location and the ones that might look it to something with 200bhp acceleration but not for 350W human powered acceleration (cycling power is in Watts, but 350w is equivalent to around 0.35 horsepower, and is the sort of power that the Tour de France riders put out on average, so you can bet that is much lower again for an amateur female)
Off topic a little bit, but I also think since everyone has started using mobile phone sat navs that more drivers are ending up on little lanes because waze or whatever thinks it’s a shortcut. Certainly round here there are long single lanes wit maybe 1 or 2 farm units on and that’s it. The other 2 sides of the triangle are A roads. You used to only see occasional tractors and 4x4 farm trucks and didn’t mind if 1 in 10 rides meant pulling in to a passing place for an obviously working vehicle but now those same roads seem to be regular cars in both directions if there’s a bit of heavy traffic at the A road roundabout. We’ve not taken the A road, so if you are going to back route down little country lanes then expect little country lane road users. (I know it’s different in areas where there are no big roads, but that’s absolutely not the case here)
