Even if it were, I doubt it would make much difference. Even most petrol cars can't get across Australia's distances in between major cities on a single refuel. It's much more likely to become customary to just have it transported by a diesel truck to the destination, and then travel by plane yourself. None of the "new mobility" is suitable for long range travel. Japan is a tiny island on other hand.
