September Driver Aggression was a little late this year, probably because the protracted summer-like weather made it easy to forget that the month had arrived. It really hit this week, though.
One hallmark of autumnal aggression is impatience after sunset. I always get honked at more when I'm operating with the lights on, and the honks tend to be a little sharp. With the generator head and tail lights, and two additional blinkies to the rear, plus reflector leg bands, I'm not hard to see. But drivers seem pushier when they pass. This continues after September. On my route, it's worse on the secondary road between Route 16 and my home in the woods than it is on the highways or coming out of Wolfeboro.
I have not commuted anywhere but here since the late 1980s, so I don't know what other riders may experience. When I commuted year-round by bike in the Annapolis, Maryland area, between 1979 and 1987, the percentage of jerks seemed pretty stable, day or night, in any season. During my bike commuting period there, it was getting steadily more urbanized and sprawled out. Of course this new growth was designed around motor vehicles exclusively. There might be token signage and a bit of width designated for cyclists in a few places, but the motorists knew that they were the top predators in that food chain. I don't think any of my old racing buddies still ride around there anymore. When I would visit from up here, even though the motoring public actually seemed less aggressive than during the early 1980s, the traffic volume made riding stressful. To be dangerous, drivers don't have to be maliciously aggressive, just self-centered and unaware.
Drivers may think that a cyclist can't see them as well in the dark. The opposite is true: a motor vehicle has powerful floodlights on the front of it, and it still makes as much noise as ever. I hear them and I see them, or at least I see the light thrown by them.
The closer passing and increased tendency to honk make me think that drivers believe that the darkness cloaks their identity. I suppose that is somewhat true, since most people's license plate lights don't work. But I have a terrible time seeing into cars and trucks in daylight, let alone at night, because of the reflections on the glass. In a lot of developed countries, hitting a cyclist day or night is basically a freebie. They don't need to be cloaked. Reasonable doubt shines down on the whole encounter.
Since I've had close encounters in the dark even when the motorist and I were the only vehicles on a stretch of rural road with decent sight lines, I think that the darkness and seclusion might also stimulate predatory instincts in some borderline folks. And I'll bet that a lot of us are closer to that borderline than we will admit even to ourselves. A twitch of the steering wheel is all it takes to assuage a little impulsive blood lust. So a super low traffic volume is not necessarily a selling point.
I've mentioned before that I feel helplessly conspicuous, riding on a trail in the dark, with my bright lights making deep shadows outside their glare. When I don't need to be seen by others, night vision goggles would be the better choice. And here we go with another gear purchase. More likely I rely on statistical probability and just keep on with the visible illumination.
