Yeah, I wish we could read the full article. It might just be that brake pad material is a miniscule fraction of PM2.5 compared to tires, so the regen doesn't much matter. Or maybe they're just doing math to write the article, rather than experimenting, and assuming that there's no regen on an EV?

Thanks. Only had time to really briefly skim it.

A bit all over the place. For one, they linked it directly with weight. But then they mentioned regen and decided to model it at 0 brake wear on EVs. Then they talked about EVs being made of lightweight materials such as aluminum, and the difference would be even larger if they WEREN'T. (what?)

It also models particular resuspension in the air as a function of vehicle weight, arguing that heavier vehicles are typically less aerodynamic -- which is probably not the case with EVs.

Anyway, interesting.

I requested the full text from the authors via ResearchGate.
