I'm a bit surprise how much talk about EVs focuses on CO2 instead of local air pollution. Global warming and climate change is an abstract topic for most people and covers a decades long timeline. On the other hand smog is something that people can see with their own eyes and feel in their own lungs. The wind changes and in a day or two clear skies turn brown and one can look at the horizon and not see mountains that are only 50 miles away. Then the wind changes again and the pollution is blown away and the sky is clear again. It is something that can happen in a matter of days or weeks instead of talking about CO2 concentrations and temperatures decades into the future.
In my opinion the primary reason to move to EV is to clean up urban air quality - reduction in CO2 is just a bonus.
