I was thinking about the music industry commercials about "You wouldn't download a car..." I think this is a category error. A car is obviously a physical object. Until 3D printers become an item in every household (and capable of "printing" a car), downloading a car is categorically impossible.
So no, I wouldn't download a car, unless this is somehow possible, in which case, somebody please show me how it can be done. I doubt I have enough RAM in any case.
