Eventually I will link all the data to a GUI front-end so I can call a stop to the loop when the user is ready with parsing.
The (small) problem now is, when testing the output in the Terminal (in OSX) when ... |

Running python script in Blender | 12,752,197 | 0 | 40 | 87,536 | 0 | python,blender | It is likely that drawcar.py is trying to perform pyOpenGL commands inside Blender, and that won't work without modification.
