I am curious to know this comparison as well. I moved across town two years ago, into an expensive house (it's not a nice house, just an expensive house) that's directly adjacent to a road with lots of traffic, and I think every day about air quality now. I also started riding a motor scooter around Denver (and across the country to British Columbia, then to Seattle, and back) and I wonder about protecting myself from road pollution while riding, especially in rush hour in cities. I wonder if an n95 would improve things for me, and I wonder how much damage I'm doing to myself by breathing vehicle pollution (emissions, brake dust, tire rubber micro-plastics), eg: 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'm 33, I'm already resigned to not-great long-term health outcomes based on environmental contaminants in food and the air. I avoid most meat (that gets me out of the factory farmed meat harm universe) and avoid most processed food, and am generally "healthy and active", but I despair of the world, for many reasons. Ugggghhhhhhhh.
