It makes sense to me based on the reasoning they provided. Public transport is one of the only places where people have to be in close proximity with strangers for long enough to transmit the virus. We know how uniquely effective public transport is in spreading the virus because we saw what happened in the one place in America where public transport ridership is widespread.
I dont think theyre saying masks provide no benefit at all. Just not enough to make them worthwhile. The calculus is different on a bus or subway.
So.....
Masks work....even Holland believes it... is the takeaway from this story
OTHERWISE...dont mandate them on public transport.
