There's been studies done specifically on people cycling to work, and IIRC the conclusion was that the overall QALY result was significantly positive. But that does depend on your baseline - for someone who is fit and active anyway the marginal gain might be small, but for the average person the 10+ QALYS you get from being active vastly outweigh the combined (run over + pollution + injury) cost. https://eos.org/articles/novel-air-pollution-study-gauges-individual-cyclists-risks https://eos.org/articles/novel-air-pollution-study-gauges-in... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2920084/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2920084/
