I'd be interested to see it, that's not an obvious conclusion to me. The health difference of an EV is a percentage increase in tire particles but a complete absence of tailpipe emissions. I would not expect tire particles to be the more significant factor, especially when the impacts of microplastics are so unknown. Tailpipe emissions are a significant problem (https://iopscience.iop.org/article/10.1088/1748-9326/ab35fc https://iopscience.iop.org/article/10.1088/1748-9326/ab35fc), and I know this is an extreme example but you can literally kill yourself by just leaving a car running in an enclosed space. EV tailpipe emissions are not fully replaced by electricity generation emissions, even if you get your power from 100% coal (and you don't). Power plants are much more efficient than internal combustion engines.

I believe this [0] is the article (with discussion at [1]). To cherry-pick two quotes to contextualize what I recalled: > "Tires release 100 times the amount of volatile organic compounds as a modern tailpipe, says an analyst." > "Moreover, tire emissions from electric vehicles are 20 percent higher than those from fossil-fuel vehicles. EVs weigh more and have greater torque, which wears out tires faster." I'm not sure how all of this works out in the grand scheme of things, or how accurate those claims are, but I think those are issues that surely deserve more looking into.

  Thanks, yeah this is pretty depressing. Feels almost unsolvable, I love public transit but I don't know how to make everyone else love it. Maybe we'll invent some perfect biodegradable tire, but it feels more likely that we'll just wall ourselves off and people (who can afford it) will drink filtered water and eat lab-grown meat and hydroponic produce to avoid ingesting their own pollution.

    > I love public transit but I don't know how to make everyone else love it By solving the following problems: - Waiting in the bitter cold / snow, or baking in the sun - Allow me to transport medium/large size dogs (most restrict animals to being in crates that can fit on a lap), without being a bother to other riders (good luck) - Reasonable wait times. Even better, do it regardless of time of day I love my car. I've been in public transit in 5 states and 5 countries, and I'm always whelmed at best. It suffices on a good day.
