It was a “rural” road according to the media. Assuming a lightly travelled road.
I visited a friend in northern Minnesota 20 years ago and was surprised to see and learn that (in that state) there was no such thing as a gravel road there. Everything had asphalt surfacing. No lines or demarcations though. Perhaps Jersey is the same.
The fact that it was after sundown is immaterial based on the aggressive/intoxicated driving reported. Even in Arizona where I spend a lot of time, many, many people cycle in the dark, with appropriate lighting, reflective gear etc.. You would be surprised to see how shorter the days are, year round, in the lower 48. 6pm-6am in a lot of spots. We are blessed with long summer days here in north western Canada.
