Ok...we are all wondering...was he walking on the correct side of the highway?
I just lost a bunch of brain cells watching most of the video and he was walking on the correct side of the road. I would also have to say that he was an obnoxious idiot yelling at people and inanimate objects along the way and ranting about Donald Trump.
Or was he walking on a curve. All I can say is that if I am coming around a curve on a highway, and all of a sudden a person comes into view, given the speed I am going at, the chance of me fully reacting and avoiding the person are slim. The person should have planned his route to walk off road. At least some bridges and roads where I lived in central Pennsylvania had walking paths off the highway for you to walk along safely.
