I have to disagree with your opinion there. Before you dig your heels in take a look at what Finland has been doing with less tech. They are going hydrogen when the rest of the EU is going electric.

Doesn't appear your description was very accurate?

Hyundai Nexo SUV carries an EPA range estimate of 380 miles in its most efficient (and least expensive) form. The Toyota Mirai sedan carries a range estimate of 402 miles.

I'll admit that the fuel cell technology is much more viable than the hydrogen combustion technology, but the basic problem remains. It is very unlikely that a hydrogen fuel cell vehicle will ever become more economical than a battery vehicle. The two examples you gave are more expensive than Teslas and less spacious. The only advantage the hydrogen offers is the ability to quickly replace the fuel, just like it was a gas car, but I don't think that will be enough for most buyers. At current prices, refilling one of these hydrogen vehicles is about $150. Refilling a comparable gasoline powered car is going to be $50, recharging a comparable Tesla is going to be about $15.
