This makes sense but I don’t put a ton of faith in the analysis. EVs grew over the past few years, but Covid also cut down on a lot of urban activity over the past 1000 days, so it’s hard to separate the two.
They compared the EV registration rates and asthma-related ER visit rates by zip code. Presumably COVID and its related effects happened pretty much everywhere, not only in zip codes with more EVs.
