I would agree.  To me it is not about one or the other.  We presently have a mix....ICE (gas driven), EV, HYBRID, NG, HYDROGEN, and probably some others.  Heck, I recall a solar car (one seater and not commercially available) that went accross Australia or the US.  This will probably be the case going forward (mix of many...with some having greater market share than others) unless or until the offering is so dominant as to make the others obsolete.  I am just glad that HPQ has its hats in both rings (EV and Hydrogen).
