Generally speaking, it's a nicely executed piece for what it is. I've been wondering when the Japanese widebody look would hit the early Viper platform. Lose the military theme, and some of it is definitely an improvement on the RT/10 styling.
How is it fake? There is video of it going down the road. And I don't have the patience to watch it again to see if I have been fooled by technology. Interesting concept, but it barely fit through the toll booth.
