It's not a showstopper, because the environmental argument for EVs is CO2 and climate change rather than PM2.5 and air quality. But it's worth bearing in mind that they only solve the former.

>>But it's worth bearing in mind that they only solve the former.

That's....almost categorically not true, the PM2.5 emissions should be solved with in ICE cars with inclusion of DPF and GPF filters, but there is plenty of cars without those still on the road. A taxi driver sitting outside of my house at night in his 10 year old Skoda Octavia diesel is definitely contributing to the air pollution around me, and that wouldn't be a problem if he drove an EV or a modern diesel with all the filters functional - but the economics of taxi driving mean they almost always drive crappy old cars which pollute a lot.

Unless they filter the tyres, this will not be "solved".

"Non-exhaust emissions (NEE) .. are currently believed to constitute the majority of primary particulate matter from road transport, 60 percent of PM2.5 and 73 percent of PM10"

Don't lower diesel and gasoline emissions matter at all?
