“Waymo’s fully autonomous, all-electric Jaguar I-PACE vehicles” Wonder if air quality improves in cities that get a large adoption of autonomous electric vehicles.

You could look at Norway for an idea, (non-autonomous) electric cars have captured the market for new cars and for long enough that the older fleet is ageing out. They are at 26% of registered cars: https://elbil.no/elbilstatistikk/ https://elbil.no/elbilstatistikk/

Except most pollution from modern standard vehicle is tire particulate dust which is worse than ICE vehicles due to increased weight and road friction. Long story short we need more walking, cycling and trains, cars aren't the answer. https://www.theguardian.com/environment/2022/jun/03/car-tyres-produce-more-particle-pollution-than-exhausts-tests-show https://www.theguardian.com/environment/2022/jun/03/car-tyre...

  I look forward to you convincing Americans to give up their cars. It’ll take decades to get the infrastructure once you do. I’m personally waiting for low-speed maglevs to catch on. In the meantime, there are 16 million Ford F150s on the road. They’re heavy too, comparable to many EVs. https://media.ford.com/content/fordmedia/fna/us/en/news/2023/12/06/see-where-americans-reside-in-the-united-states-of-f-150.html https://media.ford.com/content/fordmedia/fna/us/en/news/2023... EVs turned political and people threw out the extra weight of batteries without comparing that to the weight of the current SUVs, etc that Americans drive.

  Don't just focus on headlines. From the article you shared: > The wear rate of different tyre brands varied substantially and the toxic chemical content varied even more, he said, showing low-cost changes were feasible to cut their environmental impact. And also > Dr James Tate, at the University of Leeds’ Institute for Transport Studies in the UK, said the tyre test results were credible. “But it is very important to note that BEVs are becoming lighter very fast,” he said. “By 2024-25 we expect BEVs and [fossil-fuelled] city cars will have comparable weights. Only high-end, large BEVs with high capacity batteries will weigh more.” And > The average weight of all cars has been increasing. But there has been particular debate over whether battery electric vehicles (BEVs), which are heavier than conventional cars and can have greater wheel torque, may lead to more tyre particles being produced. Molden said it would depend on driving style, with gentle EV drivers producing fewer particles than fossil-fuelled cars driven badly, though on average he expected slightly higher tyre particles from BEVs. Once we've stamped out emissions from ICE vehicles, we have a new goal: stricter regulations for tires. Developing countries often have less strict tailpipe emissions standards than developed ones. They'd also benefit from large-scale EV adoption.

  Tire dust doesn't seem to contribute to smog. https://en.wikipedia.org/wiki/Smog https://en.wikipedia.org/wiki/Smog only mentions burning tires.
