The thing people dont realize is no matter what you power the cars with, there will be more and more arguments.
Example: If you made all cars electric, then you would need more coal to charge electric cars which means is more pollution.
Example: If you made all cars water powered, then the gov would make it illegal to use rain water and make you pay for water and we will run out of water eventually.
No matter what way you power a car its going to pollute more or cause more or new problems.

My thinking is that most of the "envronmental" concerns with cars are really just trumped up trojan horses. On balance, I'd say cars do very little damage to the environment throughout the entire value chain. Where ther eis damage, you can usually find, like in the BP case, either Federal failures or direct Federal involvement.
The thing that "some" of a particular stripe have with cars has much more to do with simple envy, a desire to confiscate other's property, and a generally hateful streak that despises the idea that somebody out there might be having some fun.
I have little doubt that a reasonably regulated market can provide whatever energy transitions will be required. Consider whaling. A combination of legislative and market pressures shut it down, for all practical purposes. The haters just need to stop hating and let the man drive whatever he chooses, subject to some basic safety standards.
