How exactly would you confirm - beyond any doubt - that contagion happened outside? Most people live most of their lives inside a building of one sort or another, so it'd be almost impossible to 'document' a case of outside transmission.

The closest thing we have is homeless populations - they spend most of their time exclusively outside - and they still get sick: https://www.sfpublicpress.org/covid-19-cases-spike-among-hom...

So making some big claim about how outdoors transmission is impossible is kind of preposterous.
