I wouldn't be quite so quick to knock hydrogen combustion engines. All it takes is a small network of filling stations to start offering it as EVE's eat into their revenues, and it has a foothold.
We have an EVE for work. Far cheaper than fossil fuel power, and pollution is moved away from the roads and into the electricity generation instead.
However, I doubt I'm the only one who feels a little dead inside every time I drive an EVE. Aside from glaring limitations placed by battery size and charging times, I crave the sound of a combustion engine and the feel of a manual gearbox.
Putting all of ones eggs in one basket is never wise. The future is likely to be balanced between EVE's, FCEV's, hydrogen, and traditional fossil fuels.
