I watch the robots build the chassis, and the vehicle is there, but it will not progress to body. What am I doing wrong?
Look closely (I know its not clear…it will be better). Your chassis slot is facing the wrong way 
LOL. I see it now. Sorry about that. I rotated it to get the stock pile closest to the input.
Also note that the slot you are connecting to externally there is only to import a finished car, you don’t need any connection to the outside world to begin the production line.
It would be nice to have a sort of “arrow” displayed when placing a station, in order to get sure to put these the right direction. The “yellow and black” arrow aren’t that easy to notice especially on higher resolutions.
