I think you have a point. But there are a few, rare cases where you could suddenly find yourself travelling at night, I guess. Like, if you're just out in the city after dark, and there's a power failure. Suddenly, you're out walking. At night. Or if you're in a car and it breaks down, and there's no cell coverage. You're suddenly traveling, at night. (I guess. I'd try to walk to better signal, but...) Camping, and you really have to go, you're walking at night. Didn't get back from the day hike as planned, so the sun's down but you don't have any gear to spend the night, you're probably going to keep going.

I guess what I'm saying is, people probably don't start off planning to travel over unfamiliar territory in the dark, but it can happen.
