Anecdata I was living very close to a busy highway, and my young daughter was wheazing when she had a cold, we had to give her medicine via a nebulizer. When we moved out to the country more, far away from any major roads, these issues all disappeared within a couple months.
A friend of mine does research on air pollution from cars - the TL;DR is you should not live within a third of a mile of a highway. The falloff is pretty sharp, but you don't want to be in that zone.
Smokers don't magically undo the damage they did to their lungs after they stop smoking. Stunned might be hyperbole, but it is at least a little bit surprising.
I'd like to imagine the stunned scientist is a scientist from another field, they show some medical findings to a guy who looks at snail butts all day and he's the one "stunned" by the findings
I use air purifiers mounted on my windows, running continuously except in the deep summer and deep winter. This makes my air contain 50-100x fewer particulates than the outdoor air. In contrast, the best I can achieve with floor air purifiers as people have them is a 5-10x reduction. The window purifiers also keep excess CO2 and VOCs out.
Do the numbers in that article make sense? 5.8g/km for tyre wear? Generally my tyres last maybe 25000 miles. So at that rate they would lose 230kg. Seems high.
Tyre, no, but regen braking almost eliminates brake particles at the speeds I drive in London. But mostly I take the train. Unfortunately the highest I measured on my particulate sensor is not near the roads, but in the tube.

Doctors used to prescribe a "change of air" in the 18-19th centuries. Maybe they still should.

I've needed my inhaler way less since the ULEZ came in.
Visiting London used to mean blowing your nose to black snot for a week afterwards, these days living in London it's pretty good.
I've not lived in London for more than a decade. I always thought the black snot was from the Tube. Is it not?
Using scientists being "stunned" should take the same amount of relevance as someone being "slammed" in article titles.

So punchline, probably a good idea to electrify all the cars yeah?
That doesn’t solve brake and tire particles. Although…rail might solve those?
