Yeah, I agree. I've been a fan of taking the lane for years. But there is the "big boat rule" too - the big boat rules. At some point, on some roads, it's just better to not be there on a bike. You may be right but you may not live to see it. This road looks like it's sort of approaching that point depending on traffic.
Where I dismount is on a country road where the speed limit is 55mph but typical traffic is well over that. There is a left turn that I need to make where there is the regular lane and then a passing lane on the right (T intersection to the left). There are often serious accidents here and in the years I've lived here multiple fatal crashes (car to car). The shoulder is wide - 10' but the passing lane takes it all up. Traffic flow behind me has to crest a slight hill that obscures visibility of the intersection until about 200' away (not long at 60mph). Almost always, I ride through the area, and get to the wide shoulder on the other side several hundred feet farther down before I make the decision to turn (essentially a U turn). About 30% of the time I dismount and wait for optimal conditions. There is no way I want to be in the middle of a car turning left, a car passing on the right and me trying to go left all with 60mph traffic around me at a known deadly intersection. Yeah, I could take the lane make a left and I just might get completely mowed down from behind too. In those cases, discretion is the better part of valor and it pays to just wait it out in a safe spot. You, however, may not have a safe spot.
