Car brake dust can be more harmful than diesel exhaust – new study: Brake pads no longer contain asbestos fibres but other materials, including a lot of copper. The copper seems particularly damaging. "Almost half of all copper in the air we breathe comes from brake and tyre wear." And of course electric vehicle still need brakes, even they use regenerative braking. And they're heavier. So the switch to electric vehicles will not eliminate road, tyre and brake dust.

Diesel Particle Filters are a highly efficient means of controlling particulate matter emissions from diesels, and the latest particle number emissions standards in Europe require the use of Gasoline Particle Filters. Consequently, particulate matter emissions from traffic exhaust in developed countries, where new vehicles have to adopt these technologies, have declined rapidly, and as a consequence, non-exhaust emissions from road vehicles now widely exceed exhaust emissions ... According to estimates … the total amount of non-exhaust particulate matter (PM2.5) emitted by passenger vehicles worldwide is likely to rise by 53% by 2030 from a 2017 baseline, mainly due to increased vehicle mileage. Non-exhaust emissions of particles arise mainly from four separate sources. Three of these arise from abrasion: brake rear, tyre wear and road surface wear. The fourth, particle resuspension, arises from road dust particles being suspended into the atmosphere by passing traffic. -- Non-exhaust vehicle emissions of particulate matter and VOC from road traffic: A review
