A series of tweets in response to some comments about the bare dashboard of the Model 3 has given us some more information about the 'part 2' of the Model 3 that he has alluded to. Apparently the blank dashboard without any gauges or controls of any kind that was shown during the part 1 unveiling on the 31st was not what the final Model 3 dash will look like. According to Musk in a reply to a twitter user named Cosmin Davidoaia he replied "Wait until you see the real steering controls and system for the 3. It feels like a spaceship."
