As a matter of fact, the vehicle itself is "zero-emissions" and "invisible to the environment".

I see your point, but first of all, it would be a very big step ahead if all the vehicles in cities wouldn't have toxic emissions.

And second, shifting the "dirty" part from the vehicles to big factories possibly makes the process more optimizable.

I agree that other form of energy should be researched, but any step in this direction is better than nothing.
