I'm glad people are looking at how to reduce the impact of tire dust. I expect we can make big improvements because it's not something we've optimized for yet. Not mentioned in the article is that EVs also dramatically reduce brake dust because the brakes are hardly used compared to an ICE car.
Well that's more complicated. Articles like this don't come out of the blue. There's an extremely well funded effort by fossil fuel and ICE car manufacturing companies to spread FUD about EVs. They are looking at double digit percentage drops in demand for their product in the decade ahead. That's going to impact them financially in a big way and they have a huge financial interest in slowing that down. And their tool of choice is misinformation. Little white lies, lots of half truths, twisted facts, lies by omission, etc.
That's not to say tire particles in ocean water aren't an issue. But the reality is that most of those particles come from ICE vehicles right now.
