People going to hate me for saying this, but…
On rural roads, where cars are rare, there’s a safety advantage to walking down the middle of the road, especially at night:
When a car approaches, you only have to shift a couple feet to the left or right (10’ is better) to be in the opposite lane (or shoulder) away from the car instead of being on the same side hoping they see you, or pinned against a guard rail blinded by their headlights and just a couple feet away from them when they buzz by.
I can’t be convinced otherwise.
