The article completely fails to mention the issue of air quality in cities. One of the things I'm most looking forward to is walking around the city centre without getting diesel fumes blasted in my face.

EVs aren't completely pollution free either. Their pollution comes from tyre wear and brake dust which is increased (compared to ICE vehicles) due to their increased weight. It might not be as immediately noticeable, but they're still turning the air dangerous. Edit: I hadn't thought about their use of regenerative braking which certainly reduces the amount of brake dust particulates. Found this literature review (https://www.sciencedirect.com/science/article/abs/pii/S135223101630187X?via%3Dihub https://www.sciencedirect.com/science/article/abs/pii/S13522...) that uses an estimate of zero braking for EVs and yet the increased tyre and road wear still makes the particulate pollution similar to ICE vehicles: By analysing the existing literature on non-exhaust emissions of different vehicle categories, this review found that there is a positive relationship between weight and non-exhaust PM emission factors. In addition, electric vehicles (EVs) were found to be 24% heavier than equivalent internal combustion engine vehicles (ICEVs). As a result, total PM10 emissions from EVs were found to be equal to those of modern ICEVs. PM2.5 emissions were only 1–3% lower for EVs compared to modern ICEVs. Therefore, it could be concluded that the increased popularity of electric vehicles will likely not have a great effect on PM levels. Non-exhaust emissions already account for over 90% of PM10 and 85% of PM2.5 emissions from traffic. These proportions will continue to increase as exhaust standards improve and average vehicle weight increases. Future policy should consequently focus on setting standards for non-exhaust emissions and encouraging weight reduction of all vehicles to significantly reduce PM emissions from traffic.

  Brake dust is vastly descreased due to use of regenerative braking. Hence why brakes last longer on EVs.

  EVs don't break often with their break disks (if even available), because they can break with the motors and generate electricity. Though you're right, they aren't emission free

  I have a 5 year old EV (with 50k miles) that is nowhere close to replacing it's original brake pads based on a recent checkup. Regenerative braking is the real deal. Also low rolling resistance tires cause less particulate loss and last a lot longer too.
