Looks real to me. And not surprising. If I was driving the striping truck, I prob'ly wouldn't stop to kick it off the line. Who gives a tree rat's a$$ ennyhoo? I'd say road crews are practical folks. That kind of energy conservation is an acquired skill.
not real on any of my jobs. all the contractors i work with use a fast go kart to zip ahead to make marks, install buttons and just clean up.
i think the squirrels is staged. the last step of that process, the machine will dump a bunch of glass beads down. gives the strips the reflective look. it is a mess. the machine overpours the beads. there would be "bead dunes" up on that squirrel.
