Here is a theory. All of the automakers have been enjoying quite the run cyclically over the past 5 years or so. GM and Ford especially. Now Ford is struggling (new CEO) and GM sales are trending downward. This tells me that in the short term they have other problems to deal with and so won't have the time or money to invest for the long term emerging market which is electric vehicles. Clearly the German auto companies especially Daimler are in a different position and it seems the Japanese are stuck in concept phase or itty bitty cars for their own urban markets. This bods well for Tesla in the long term.
