wouldn't it be risky to ride behind a potentially infected rider? after all you'd be breathing in their exhaled air, or would the speed and wind dillute the aerosol quickly enough to make it harmless?

I read that italy banned bicycling in affected locations to avoid accidents that would further strain their already stressed health care system. sorry, no source.

Basically this. It's a probability thing though.

Indoors, air is stagnant and sneeze droplets can float around for a few hours.

Riding behind another cyclist requires poor luck for enough of their sneeze to impact you.

It's still cool enough for me to wear a face mask too, so that's another (hypothetical) risk reducer.

Plus, a cyclist is a good signal someone doesn't have active respiratory disease.
