Not that I love ICE cars or anything but isn’t the big health impact from heavy vehicles like delivery trucks and, more importantly, from the rubber particles caused by car tires? A problem that in general worsens with BEVs since they’re, on average, heavier? I’m sure smell will improve significantly, but breathing tire and road dust is the main health concern as I’ve understood it. Most other pollutants get rather effectively caught in the catalytic converter, aside from CO2 but that isn’t unhealthy per se. CO in small doses out doors also isn’t a big issue. NOx bad for nature but likely of low harm to humans. Etc. Someone please correct me if I’m misinformed.
Note that all these studies are VERY recent considering how long we’ve been running vehicles with rubber based tyres. I also strongly dislike how the report you linked only focused in properly on brakes, which I know full well are vastly superior on hybrid and BEVs due to regenerative breaking and the restarted use of drum-style breaks. And more or less dismisses the tyre aspect, which is extremely irresponsible in my opinion. Granted though that it’s arguing from a “Are BEVs worse than ICE vehicles?” so I can excuse some of it.
Naively, it feels like most of the issue is from a small number of extra sooty vehicles. But that belief is probably just because of how visible it is. The brake/Tyree dust isn’t visible because it is more spread out.

Sure, I’m not saying they’re somehow worse than ICE vehicles, they’re demonstrably not. But particulate matter is the big health issue and not gases, and more and more studies is highlighting that tires are very big on particulate matter. https://www.theguardian.com/environment/2023/feb/23/health-impact-tyre-particles-increasing-concern-air-pollution
