governments wont even allow it, who'd buy fuel with a car that needs basicly no maintenance, noone would need power becouse they have their own powersupply. besides, no maintenance on the powersupply? before i even consider buying a car like that i'd like to know for damn sure the thing wont explode on the middle of the road

anyways, governments will miss a lot of money if this hits the market, so they wont allow it.
