Wouldn't count on it. EVs tend to be heavier, so we can expect more dust from tire wear and brake wear. Not to mention road wear. Roads, by the way, are frequently asphalted with the ash leftover after incinerating waste, which I suspect will contain a carcinogen or two of its own.

Tire particulates tend to be bigger and heavier than those from fuel, settling on the ground rather quickly. Brakes are only seldomly activated in EVs, so much so that rust is an issue.

> ash leftover after incinerating waste

This 'fly ash' and 'bottom ash' are both so toxic that regulations don't allow putting them in landfill.

So instead we mix them in with concrete and asphalt in roads. I'm sure it sounded like a good plan to whoever was going to have to pay to deal with the toxic waste otherwise...

Nonsense. EVs and hybrids leverage regeneration for nearly all of their lifetime braking energy use. Its commonplace for EV brake pads to last the life of the vehicle today. Exceptions exist, but those are for particularly hard-braking drivers. Our Prius ran 200k miles on the factory brakes, for example.
