The 'I believe in science' crowd completely dismissed the data several years ago (this is not recently discovered) when confronted with the data that particulates from combustion engines had been mostly eliminated and that most particulate pollution was actually from tires and brakes. And further, BEVs, with their higher weights, actually produced more particulate pollution than ICE vehicles. Instead, they insisted that BEVs were clean, because 'science'.
Now, the eco groups that have always been anti-car are pushing this data as BEVs have gained market share. They're never going to be happy. Bicycle tires and brakes have the same issue as well. Even the soles on our shoes. This is why every sane person needs to stop listening to the eco lobby. They're extremists that will never be happy and never look for practical balance. Reducing pollution is a good goal. Net Zero is an impractical target lest we drastically reduce human population and give up nearly all modern conveniences.
