I do actually feel safe getting in public transit while covid’s ongoing, and I’m in Tokyo (and taking two of the busiest lines in the world as part of my commute - Chuo and Yamanote). At this point it seems obvious to me that having windows open, everyone wearing masks, and everyone shutting up, is sufficient to make public transit safe. Because if it wasn’t Tokyo would be in a _much_ worse situation. I fully admit I don’t have rigorous data to back this up, but I kind of can’t see how it could be otherwise.
