Future (transportation) fuel

The fuel of the future will not be an OR but an AND situation.

As we speak, electricity vehicles are being praised to be the future. I think HYDROGEN is a better bet. 

In the future we will have a diverse fuel economy of electricity, hydrogen and even fossil fuels.
Probably it depends on specific situations, which fuel you will be using on that certain point. 

If I would make a wild guess it will be like:
- Electricity: public transportation, private transport for small distances [poor/middle class]
- Hydrogen: private and professional transportation [middle/rich class]
- Fossil fuels: This will be used in exclusive transportation vehicles [rich class]
