A few weeks ago, I observed in a post about aggressive driving in early autumn, that motorists on my route seemed particularly irritable on a small secondary road near or after dark.
Murphy's Law as it relates to motorists passing bicyclists states that the drivers will synchronize their speeds so that the pedaler and the motorists are all squeezing through the same space at the same time. In daylight this is annoying enough. At night, it is particularly hard on drivers, blinded by oncoming headlights, trying to find a safe passage. Those of us who drive, think about how often you maneuver on faith alone, because the glare has eliminated all sight of the roadway at a time when you really can't stop. Now put your pedaling self into the picture.
For the majority of situations, a decent set of lights and some added reflective material will make a cyclist adequately visible. A decent set of lights also provides enough light for the cyclist to see the road ahead. But when the road is narrow, a little hilly, and bendy, a cyclist presents much more of a challenge to drivers.
By the law, cyclists in many jurisdictions have the right to take the lane to prevent passing. This is a good idea a lot of the time anyway. It isn't always a good idea, though. You have to develop your own judgment about when to herd, and when to let 'em run.
Unfortunately, impatient local drivers will perform the most insane maneuvers to pass a cyclist, day or night, on my route. But even the ones who are somewhat more likely to take a moment will seldom take more than a moment before launching themselves around me. This factor more than any other impels me to change to the park and ride when daylight grows short. Faced with the sudden threat of each other, motorists will blame the easier target: the guy on the bike.
Is it a form of surrender, to give up the road because motorists don't have the patience and judgment to behave decently around other road users? Yes. But the death or injury of a cyclist would serve no purpose. It would not advance the point of view that motorists should learn to drive with more generosity. Someone would point that out, but it would join a jumble of other assertions that would leave us all where we started -- except for the poor schmuck who had gotten slammed by an armored vehicle.
Evolution moves slowly, on a broad front. We can each help it along in ways we'd like to see, but ultimately an individual's survival comes down to moment-by-moment combinations of skill and luck. Accumulated skill can enhance luck, but uncontrolled variables will remain. If you want to see what the future turns out to be like, you have to survive to get there.
