They probably will at some point, except for now they are trying to make them more appealing to stop thousands of people dying from pollution primarily created by running ICE's in our cities.
They probably will at some point, except it isn't necessarily 'fuel' in the same way petrol or diesel are (unless 'bio fuels')? Eg, how you use your electricity should be down to you shouldn't it, be it for cooling you beer or running your car?
Just the same with how you use your alcohol, be it in the food you cook, in a glass to drink, getting stickers off things or a fuel in your dragster or camping stove? ;-)
I'm sure you do. ;-)
