With current technology, the quote only applies if it's a fuel-cell electric vehicle with very good air filters. In that case the polluted intake air is filtered and exhausted with water vapor. So, the dirty air that came into the fuel cell, is filtered on it's way out, and is cleaner. The air was never burned or combusted, but simply contributed to a chemical reaction.  |
The quote I initially referred to applied to an internal-combustion-engined auto, not a fuel cell. It was a long time ago and made reference to the modern car they were testing (think it was a Honda but not certain) had cleaner exhaust than what was found in Los Angeles and particularly Mexico City. I remember laughing about their claim that you could help clean the air by driving more.
Whether they were right is another issue, but what I read definitely applied to an ICE.
