Very interesting indeed: "In fact, more small-particle pollution comes from the action of car brakes and tyres than from the exhaust fumes of current internal-combustion engines – a testament to the effectiveness of catalytic converters and to modern fuel-injection systems."
Then electric vehicles are not nearly as clean as the public thinks they are: every two Teslas or electric cars on the road produce more small-particle pollution from the action of their brakes and tyres than the total small-particle pollution of one internal combustion vehicle (engine, brakes, and tyres).
Unless you look at CO2 emissions :)
Regenerative braking largely minimizes conventional braking on Teslas.
