Well this was interesting to me, thanks for sharing. Looking at https://www.emissionsanalytics.com/news/do-no-harm it looks dependent on what you're optimizing for (and not driving like a hooligan helps, hard acceleration and braking wears tires more).

Even so, I still find that the fewer cars there are, the easier it is for me (and my kids) to walk and bike places safely, helping us be healthier (and not reliant on drugs like Ozempic) which was the real point of my comment.
