Tires and brakes still contribute to a lot of particulate matter pollution even from EV's, but they're at least a step up. The best EV's are still eBikes though

- tbrownaw 9mo agoTires yes, but EVs tend to have regenerative braking which will reduce brake particulates significantly.
- chupasaurus 9mo agoThe study is about NOx levels which have nothing to do with tires or brakes.
- swsieber 9mo agoI mean, it kind of is. But I'd say the framing is about general air pollution, and they happen to use NOx levels as proxy indicator. So from that perspective, I think it is important to note that there are other types of pollution that go up with electric cars.
- davidw 9mo agoOk, but tire pollution is still a problem: https://grist.org/transportation/electric-vehicles-are-a-climate-solution-with-a-pollution-problem-tire/ https://grist.org/transportation/electric-vehicles-are-a-cli... https://caltrout.org/news/did-you-know-your-cars-tires-could-be-harming-salmon/ https://caltrout.org/news/did-you-know-your-cars-tires-could...
- gruturo 9mo agoTrue. But there are 2 ways to read this: 1: Yes, let's stick with ICE cars and die of preventable illnesses because EVs are only a massive improvement, rather than absolute perfection 2: Hey let's take this massive improvement and enjoy enormously cleaner air I meet way too many people from group 1 unfortunately.
- davidw 9mo agoThat's exactly what I wrote: "it's a step up".
- montalbano 9mo agoRecent research suggests the issue is much less concerning than previously estimated. https://www.ch.cam.ac.uk/news/illusion-truth-surrounds-inaccurate-tyre-pollution-figures https://www.ch.cam.ac.uk/news/illusion-truth-surrounds-inacc...
