that's pretty insane. i think it's a combination of just waiting to get the right shots with no one in them, and using vfx to mask cars and people in some shots. if you pay attention a lot of the shots seem weird because of context but they don't pan around far enough to see if there actually are people just out of the shot and they only last a few seconds so no one walks through the shot. highway with no cars is pretty nuts and hard to imagine, but i don't know phoenix, maybe there are certain areas he knows where there's no traffic at certain times of day.   total bullshit but probably the dude who made the video trying to stir the pot. great video.
