Well I read the article and got excited about eliminating internal combustion engines...

The source says 5-19% reduction which is solid but pretty far off from "hardly any" in my view.
Isn't that number for the total particle emissions, rather than just for emissions from the brakes?
If you have trouble reading or understanding english then I apologize and of course please continue to get the information this way if that is best for you. I mean this seriously and not as an insult. I had a TBI once and had a hard time parsing information like this for a couple years after.

NOx emissions kick in as the main pollutant much earlier in such places.

No, "PM10 for non-exhaust sources per km" and then the following line has more info about about pm2.5. Please just go read the thing it's not our duty to quote it at you piece by piece to disprove your assumptions about how good EVs are especially when the article is right there and not even long or very technical. If you have trouble reading or understanding english then I apologize and of course please continue to…
I wanted to find an account of what the biggest sources of PM2.5 are in the US. This article discusses traffic fumes (24% of PM2.5), but I was surprised to learn that by far, the largest source of PM2.5 - 45% - is “unspecified sources of human origin.” Where does that stuff come from? Well, it’s created in the atmosphere via secondary reactions between agricultural NH3 emissions, SO2 and NOx emissions from shipping a…
The other thing people don’t often talk of is PM2.5 inside their home while cooking. Lot of people have poor ventilation or insufficient air movement capacity in their kitchens.
Cooking fumes are the primary pollutant in my life, and honestly is one that I struggle with since I have severe asthma but love to cook. I do what I can, but this is something I wish was taken more seriously in society because there's a huge economic hill to climb to solve it yourself vs having to deal with what's available on market.

From the food, or the fuel?
but this is likely a very small factor for nearly all people. cars (oil) and electricity generation (coal and gas) create most of the harmful particulate matter in the air (and water and ground), so that's where we should focus our anti-pollution efforts first and foremost.

Slightly? I barely use the brakes ever. Whoever is out braking in their EV all the time should have their DL revoked
Where I live residential neighborhoods have 4-way stops at every intersection so preferably everyone would be braking all the time, yes. They obviously are not and cruising through stop signs (and sometimes killing children!) is the norm. If EVs encourage this driving style that is another strong point in favor of "electric cars can't solve the problem of cars."
You reap what you sow. A grid of 4-way stops where the traffic flow is not appropriate for them is a textbook perfect way to train drivers to habitually roll stop signs.
I swear sometimes it seems like urban planners are hellbent on re-learning everything they learned in the 1920s.

I wonder how important the raw amount of emissions is. Density should decrease at a cubic rate of distance, so being close to a small source of emissions might be worse than being somewhat far from a heavier source.
