For what it's worth, I grew up in a polluted city, studied climate science in school, and work in renewables. It's not that I don't think air pollution is a big deal, it's that I don't think the idle car secret police are a good way to deal with air pollution.
CAFE standards? Great. Point-source air pollution tracking and fines, from factories and such? Cool. Renewables-backed electric cars? Great. Cleaner, low-carbon grid mixes? Yes. Divestment from fossil fuels? Cool. All of these are actually hugely beneficial actions, but they don't require the state to turn citizens into informers against each other for petty everyday actions.
Air pollution is your typical tragedy of the commons situation, borne of the collective actions of millions of people living in an industrialized society and just trying to live their lives. It's not the sort of thing worth putting a bounty on, IMO, at least not at the individual level. At the corporate level it's a different story, cuz that's a cost of doing business and accounting for externalities and such.
All of those are better solutions than criminalizing trivial behavior and fostering a culture of distrust, all for little to no measurable improvement in air quality, just to satiate the political agenda of a politician. It's the difference between cheap political points for low-hanging fruit, vs doing the actual useful and hard work of setting sustainable climate policies that don't regressively hurt the working class while also turning citizens against each other. It's that sort of blindness to the needs of the average person that makes this sort of thing elitist.
