As someone who remembers the smog that we used to have here in Southern California, I don't mind leaving the trad-gas in my dreams if I can keep the massively improved air quality in my reality.

This is a myth. While tailpipe emissions are lower, evaporative emissions are higher. At best it's a draw.

You're seeing less smog because people are driving modern cars with modern emission systems because we live in the future, smog-producing vehicles have been taken out of service, and drawing conclusions based on mere correlation of the two. It has nothing to do with ethanol.
