In other news, US automakers are rolling out new vehicles that burn rubber at twice the current rate while offering a blistering 15mpg.

    Electric vehicle are major culprits, no? They literally weigh tons more than ICE, a lot more friction between rubber and road and therefore more tire wear?

    If they're using the stock low rolling resistance tires, there's actually less friction.

    Not to say that's necessarily a good thing, since it's easier to spin the tires with all the extra ev torque.

    The computer stops you from spinning the wheels. I chirped the tires on my CRZ making a measly 150lb-ft way more than I've ever chirped my MachE GT at 600lb-ft...which is 0 times. I think most the tire wear is going to come from turning/cornering in this case.

    Lol the 80kw motor in my Ford c-max chirps the tires every 3rd takeoff, and like 90% of the time when roads are moist. Could just be because my model is a compliance car, but the traction control suuuucks.

    It's a little trickier than that. My Mustang MachE weighs about 4900lbs. The Ford Escape, a similar vehicle by the same manufacturer weighs 3300lbs, so my EV is about 1.5 times more car than the ICE equivalent. However, my car uses regenerative braking, and there is a huge reduction in brake dust from EVs, which some quick googling says can make up to 55% of non-emmission related airborne particulate matter in urban areas. Not to mention that the EV releases 0% (or maybe like 30% depending on the power infrastructure) of the "tail pipe" emissions of a comparable ICE car.

    It's all kinda moot since the majority of brake dust and tire particulates come from the 80,000lb semi trucks.

    I'm not doing a deep dive on any of the particulate emissions listed. It's a complex field, and I'd consider those numbers as "factoids at best" but it a least gives us a ballpark number.

    Then you gotta ask yourself how you’d compare microplastics vs other types of pollution.

    Tricky question, gets back to the whole, "I'm a part time internet shit poster and not a pollution expert" bit. I think that the impacts of microplastic pollution is serious and needs to be reduced where possible and regulated when it can't be reduced. I also think that the concern about MPs is valid and serious, but a bit overblown. I'll leave you with the last bit to think about as well: There will never be another person born on this planet without microplastics in their body.
