For many people, hydrogen fuel cells might be a better option than electric batteries. To convert the hydrogen to energy, a device called a polymer electrolyte membrane fuel cell first strips electrons off the hydrogen atoms, creating positively charged hydrogen ions. Those ions combine with oxygen from the air to form water as a waste product. The electrons provide the energy that drives the car’s electric motor.
Eventually the system will come to "resent" the space needed by personally driven vehicles, and taxes/registration on them will escalate accordingly.
