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?

Chevy Suburban: ~ 5,700–6,100lbs

Model 3: ~ 3,860–3,900+ lbs

Suburban is about 1.5–1.6× heavier than a Tesla Model 3.

The Chevy Suburban has been one of the largest vehicles on the market since 1934. [1]

If you wanted an EV to match the Suburban it would probably be that Cadillac Escalade IQ in terms of size, comfort, and towing capacity -- that's got a curb weight of 9,100 pounds which is 1.5x heavier than the Suburban.

I'd think the BMW 3 Series has a similar vibe to the Model 3 and that has a base curb weight of 3536 which is about 10% less than the Model 3.

[1] it's the oldest nameplate that's been made continuously
