A junked out vehicle, filled with junk. Was it a redundancy or an amplification?

Also, in this town I saw a man walking along the highway. He was wearing a backpack and carrying a one-gallon container of water. Every time a car would pass by, he’d raise the water container as a wave to the drivers. (This is not a part of the state where people just…hike.) (So I am not sure what his deal was.)
