One thing that caught my eye is the study is simply modeling the increased PM10 and PM2.5 based on hypothesised influence of weight difference using gas and diesel cars (from 2013) as a basis.

Obv. I haven't read anything but the summary but the core assumption means it's an extrapolation and not measuring actuals.

For example, while EVs accelerate faster, regen braking massively reduces brake wear - the lack of mention of regen in this extrapolative study seems a huge miss. Also EVs typically don't have the same tire material - they use low rolling resistance tires which do better on particulates.
