In fact, the second link for me in that Google search mentions this study, as well as others suggesting the physical and mental benefits of cycling outweigh the pollution you breath in: https://www.standard.co.uk/optimist/theairwebreathe/cycling-...
> Our study also found that there are simple changes that could reduce exposure to emissions for professional drivers, such as keeping windows closed when driving, or changing routes to avoid tunnels. Having an air-tight vehicle cabin can also play an important part in reducing driver exposure. Technological fixes such as specialised in-vehicle cabin pollution filters may also be a short-term solution to reduce exposure for professional drivers.
