He is certainly moving along but what makes it more obvious is the car taking the video isn't going that fast, just been overtaken quite quickly by a Toyota then that Navara with a big trailer on. I would say the Audi is probably doing 120 ish. Doesn't even have any headlights on, not that's it's dark but cars are more likely to spot you. Won't last long before somebody pulls out if they regularly drive at that speed.
