regenerative braking is going to offset added weight of electric cars.
the article from the premise however specifically notes that it disregards pollution contributions of the impacts of EV on 1. powerplants to make the electricity and 2. mining and manufacturing of EV major components such a batteries.
While it's possible to scrub pollution from powerplants if you don't care about the cost of electricity you still have the much nore important issue of CO2 (G warming pollutant) which the article also does not address. Far more important than PM2.5 pollution imho, unless you're addressing just the cars within major metros like NYC, London, etc.
In this regard, point #1 is a major major negative mark when you compare EV versus a well designed gas powered hybrid. .
