Knowing nothing, my bets would be: 1) There is nothing sexy about the car. Tesla cars aren't just electric cars - they're also fantastic cars. Tesla makes a great (amazing?) car that is electric, rather than a an electric that may be a great car. 2) Yep, fueling infrastructure. You can charge your electric cars at home, at the office; the supercharger and battery swap stations; that Tesla (AFAIK?) charges your car for free... Where do you need to go to get hydrogen fuel? There's also an analysis - maybe in the Wait, But Why? on Tesla - as to how you can't sell alternative vehicle stock from normal dealerships; it just doesn't make enough sense to the dealer, but ATM I don't remember the reasoning. Also AFAIK, Mr Musk has a good write-up on why hydrogen fuel isn't The Thing. But mostly #1, IMO.
