I was in San Jose Costa Rica a couple years back - their downtown was unwalkable by me because of all the exhaust I felt as though I could hardly breath, I could I'm sure I just wasn't used to that level of CO - I had to go a couple streets over to a less busy street.
Its really sunny here its very close to the point where its the smart money solution to have solar panels and have one electric and one gas powered car. Right now I've got dollars bouncing off my roof and I'm spending money on gas I shouldn't.
Does this make sense as you move further north probably not, and we still need to figure out this battery thing, but it seems like we are much closer. In my neck of the woods there are lots and lots of Teslas - they are ubiquitous here.
There are a ton of hybrids too - you hardly ever smell exhaust at a traffic stop and its hot.
Mining and processing the lithium, cobalt and manganese used for batteries consume a great deal of energy. A Tesla Model 3 battery, for example, represents between 11 and 15 tonnes of CO2.
Plus the child slave labor involved in mining these materials in Africa. But that doesnt matter to the left.
And the left pushes ethanol gas which is worse than pure gas..

Lived in the LA basin for a year back in 1976. My work took me from Long Beach to San Berdo and all points in between. The air quality sucked to the point that you could taste it ... I had a chronic sore throat (off & on) the entire year I lived in the LA area. In more recent years when business/personal travel takes me back to LA I've noticed a much improved air quality.
You are right; solars usability is location dependent. When the panels are covered in snow and ice for months they dont work too well...or last too long.
My bet is down in Costa Rica it wasnt CO2 bothering you...it was actual pollutants. Not a trace gas like CO2.
