Great read, and I agree with the tone of the article. My impression goes something like this:
All these really cool things are possible, but most are expensive up front. American car companies (and to a lesser degree, the rest of the industry) are dragging their feet because they don't want to lose what they have. Of course, their foot-dragging is causing them to lose it one piece at a time. No-one who has the money and political capital to make something happen has the guts to do it.
Prediction? The company that takes us off gasoline won't be a major company, it will be someone new with nothing to lose (Tesla? This guy? Who knows.)
