There is still a problem with electric cars, the tires also produce particles that are carcinogenic.
"Electric vehicles emit no NO2 but do produce small particle pollution from the wear on brake discs and tyres and by throwing up dust from roads. A recent European commission research paper found that about half of all particulate matter comes from these sources."
- wongarsu 7y agoEVs use their brakes less because of regenerative breaking. The particulate matter of tires is for the most part comparatively big an heavy, so a larger part of it stays near the ground and gets swept away by rain, and could be cleared in problematic locations by wetting the street (also bigger particles seem somewhat less problematic for health). You're right that EVs don't fully solve the problem, but they are a giant step in the right direction.
- WorldMaker 7y agoEVs are also generally concerned about overall weight and have smaller tires on average than non-EVs in their respective categories.
