Speculations? My guess is asking permission to add Starman to the Elite Dangerous galaxy. To this end I even researched how long its expected to survive in orbit and, assuming structurally it doesn't disintegrate, it appears the orbit itself is good for quite a few million years with pretty low chances of impacting another object. Of course, that's assuming Mr Musk or someone else doesn't retrieve it as another publicity stunt and put into a museum at some point in the future..
If this is the case, then personally I don't think Starman is important enough an event on our human timescale to immortalise in the game.
Thoughts/opinions?
