a) There is no other stuff in terms of dense/energy/danger like gasoline/gasoil b) gas must be kept under pressure or kept to temperatures where pressure is moderate, leaks are often not easy to recognise c) electricity in terms of batteries/accumulators - based on chemical reactions - have the risks of low inner impedance, that means: if the whole energy of Your battery reacts in half a millisecond into energy, because of an inner short-circuit or alike, You and Your car are never more, even not to identify. Gasoline/gasoil needs much more time to react(==burn). This low impedance problem is the *real* reason, why icreased energy dense of batteries or accumulators, wich have much more energy density as the usual and are still developped, can not be let into public release...
