I don't understand the rationale of your comments. An electric only car would need a larger (heavier) battery for a longer range too, is that also wasteful in your view?.
We need technologies like these to fill the gap until we can depend solely on batteries

There's nothing irrationale about that. One disadvantage of the battery technology is that "half-filling" a battery doesn't half its weight. A Tesla-sized battery pack for 100 km daily trip wastes lot of energy (several hunders of kilograms of dead weight, even regenerative brakes cannot recovery all the kinetic energy.)
