I understand the sentiment, but I’m willing to bet that it’s more likely that the average person will die in a car than on a bike.
Yes, there are risks, and yes cycling infrastructure can absolutely help to reduce those risks, but in the greater context I think cycling is still the better option in more ways than one.
For instance, cycling can reduce the chance of the #1 cause of death (heart disease), while cars increase that risk. That alone would make cycling better for health and longevity, even with less than perfect cycling infrastructure. 😀
