Minor nitpick, but tailpipes aren't the primary source of emissions. The study is about PM2.5[0]. which will chiefly be tires and brake pads. Modern gasoline engines are relatively clean, outside of CO2, though diesel engines spit out a bunch of bad stuff.

How do EVs fare in this regard? Brakes are used significantly less, but the additional weight from the batteries chews through tires faster.

Why does everyone immediately pivot to EVs on this subject, instead of (looks around) gargantuan SUVs and trucks everywhere, due to peculiarities of US policies regulating SUVs more leniently than cars on fuel efficiency?

Why does everyone immediately pivot to SUVs on this subject, instead of (looks around) gargantuan Tesla Model Ys that weigh as much as a Ford Bronco and EV trucks everywhere, due to peculiarities of US consumer habits and the demand for huge vehicles to pick up groceries?

No, they're crossovers. Closer to a hatchback.

I mean, they're literally called SUVs. https://en.wikipedia.org/wiki/Crossover_SUV

Even https://www.tesla.com/modely uses the term "Electric Midsize SUV"

huh well TIL, thank you. My definitions of Sports Utility Vehicle are outdated. They have almost no clearance, and the suspension is not tuned for anything more than small washboards.
