SensorDeviceClass for Vehicle Energy Consumption?

As we have more and more integrations for electric vehicles, would it be useful to add a dedicated SensorDeviceClass with Converter for vehicle energy consumption? E.g., kWh/100km, miles/kWh etc. Or are there any other sensible way of presenting things this.

Some initial work in implement vehicle energy consumption units · home-assistant/core@14d0020 · GitHub. Not sure if this should be vehicle specific or if we should do “distance energy consumption” or similar.

Now renamed to EnergyDistance as it may be applicable to other forms of energy consumed by distance - Comparing home-assistant:dev...jschlyter:energy_distance · home-assistant/core · GitHub

Any discussion can continue at Units for energy consumption by distance · home-assistant/architecture · Discussion #1163 · GitHub.
