It is good for now, given battery powered vehicles' advantage in terms of regulation. My guess is that as they become the majority of vehicles over time there will be an interest in efficiency regulation similar to fuel economy for ICE engines. There is already an interest in taxing electric vehicles differently given the eroding base of road-building taxes based on hydrocarbon fuels.
