In a recent statement to the press, the CEO of Tesla made it clear that it now looks like Tesla would ship about 50,000 cars in calendar 2015, not the 55,000 he had previously indicated. He then quickly boasted that he continues to be confident that Tesla will ship 500,000 cars in 2020 (a 10x increase in five years!). These statements spawned many articles in the press questioning the reasonableness of the CEO’s projections, particularly since he has a history of over promising.
