It’s also only 5% of the new cars registered in California alone, by your own data.
That's literally an insane number of cars. Its literally more vehicular emissions than 60 countries.
At this point I'm genuinely interested in why this headline is breaking peoples brains. It seems like people are mostly having an emotional reaction to the fact that the study is critical of inhalers, and then, its a circle jerking/ dog-piling, what-about-ism, or the relative privation fallacy.
Its a bad thing that oil-tankers exist. We should all probably move on past internal combustion engines. It doesn't change the fact that, apparently, inhalers represent a quite substantial source of emissions.
Its not at all additive to dogpile on a headline that makes that point. Two things can be true at once.
