Everytime I see the videos, I want to go out and buy a VW/Prosche or Audi that is made in a factory (not a plant) where everyone wears white coveralls, the robots are run/guided by people and there is not a sign of of oil or grease. I think the guys that work there build the detailed models/scenes must do it as a hobby and go there to install them on their annual 4 or 6 weeks vacations. - Imagine over 13 km for tracks for trains plus the roads, bridges and more personal effects.
