Everything factors out to a matter of energy density, not only of the vehicle itself, but also the underlying energy delivery infrastructure.
It's possible, but expensive, to adjust the infrastructure to compensate for lower energy densities of the vehicles. The bottom line is that petroleum products (gasoline/diesel/jet fuel) currently enjoy the highest energy density of any technology, not only on the vehicle end but also the infrastructure side. Until that changes, I'm afraid we will not see any significant advances in alternative technologies.
As is being seen in the popularity of hybrid vehicles, the best we can hope for is to increase the efficiency of the vehicles.
