You sure do like an argument. Or getting the last word on every filibuster. And I say that as someone who loves the sound his keyboard makes. So have at it after this post.

Yeah, I understand the concept of dark adaptation. We did the nighttime training maneuvers in the military, including nighttime orienteering. Our squad won that competition -- despite my nearly complete lack of a natural sense of direction because I can read a compass and topo map and could see well enough we didn't need the red or blue filtered flashlight and none of us smoked cigarettes (which got a rival squad eliminated by an ambush -- those lighters show up for a mile or more across the Camp Pendleton terrain in some areas, and even a glowing cigarette tip can be seen from a surprising distance with dark adapted eyes).

And you're overstating the differences in a typical suburban and urban area. It's never dark enough on most of our MUP for anyone to attain totally dark adapted eyes. At a minimum there are utility lights within a quarter of a mile of practically every point along the MUP. The one exception might be that stretch with a heavy tree overhang that feels like riding in a tunnel.

Most of the pedestrians I see along the MUP at night have their noses buried in their phones, their faces lit up blue. Nothing my bike lights do will make a difference. The handful of folks who aren't using lights and reflectors aren't likely to stumble off into the non-existent woods and be eaten by non-existent bears because they were blinded by bicycle lights. The biggest risk to pedestrians is stumbling 50 yards down the bank into the river while playing Pokemon Go.

I yield the remainder of my time to the gentleman from Colorado.
