The difference in pollution between electric and ICE cars might be small, since most pollution is so-called "Non-exhaust emissions", like road surface wear, tyres and brakes:
From link > [We] performed some initial tyre wear testing. Using a popular family hatchback running on brand new, correctly inflated tyres, we found that the car emitted 5.8 grams per kilometer of particles.
That is 5.8kg per 1000km!!! An article that makes such ridiculous claims can be dismissed as trash. A small car tire weighs about 7kg[1], so absolutely no tyres or brakes left after less than 10000km.
Also note the the vast majority of tyre particles are larger than 50um.
By weight, I would guess less than 1% of wear by weight was < PM10 - see graph[2] from the first paper I found that measured tyre wear[3].
Edit: I'm not saying tyre and brake particulate doesn't matter, but I am saying that link looks to be solidly in the stupid camp.
"Data from the UK National Atmospheric Emissions Inventory indicate that particles from brake wear, tyre wear and road surface wear currently constitute 60% and 73% (by mass), respectively, of primary PM2.5 and PM10 emissions from road transport, and will become more dominant in the future."
So I'm not saying that website isn't trash (it definitely looks dodgy), but the particles being emitted could mainly come from the asphalt and not the tyres. Though this seems unlikely as tyres are much softer
Electric cars use their brakes far less. If you play around with the regenerative breaking you can handle 90% of situations without ever touching the brakes
And your article is only talking about local particulate pollution, let’s not forget the bigger issue of CO2
