Why?
Because mother nature has been breaking down, compacting, and extracting the energy into the form of crude for millions of years.
We currently have no technology that can replicate this process in a manageable/renewable time frame. Until that day comes we will be on crude based engines.

This is only one of many ways of turning biomass into a form of hydrocarbon crude.

Electric is the future for simplicity and everything but batteries have a long way to go along with creating the electricity cleaning/efficiently to power the cars.
The same key to electric cars hold true for HHO in that the most efficient way to split water is with high-temperature electrolysis but that requires nuclear reactor like conditions to even compete with natural gas or coal.
The difference might come in the form of solar energy splitting but then it is more likely and stable to just use the solar electricity directly to the car instead of HHO and having to store hydrogen.

Batteries are the Achilles heel of electric portable motive systems. People seem to think that time and money will bring down the cost of batteries while increasing performance much like current electronic development. But battery development does not follow Moore's Law. It is constrained by physical laws, and battery development has been and will be incremental and not geometric.
