you missed the point, when GM surpassed Ford a hundred years ago, Ford was as new as Tesla, and GM was a newer player with fresh ideas that better fit the market, and nobody saw it coming, especially Ford. You see, GM was run by a managerial and marketing genius, and Ford was run by Aspergers. (I can say that, I am one)
Ford is the only one of the so-called “big 3” who hasn't filed for bankruptcy at least once, but there are lots of other US auto manufacturers, and many of them haven't filed for bankruptcy.
