I'm honestly all for a healthier way of running cars, even though I'm sure big business would go out of its way to prevent this from happening if they can. I do agree that it'd be a good idea to find countermeasures for the pollution, but chances are those things aren't 'profitable' so the majority of people (who can actually do something) won't care. Still worth pursuing.

Sure, contributing to taxes is something, but nearly everything does that. I'm sure there's plenty of things the world would be better off without that have sales taxes.
