I saw, what looked to be a teenage girl, or maybe a bit older, wearing a mask, while riding a bike outside, by herself! She was riding along side a busy road, where there aren't really any people walking or riding on the sidewalk.

I see countless people wearing masks, while driving in cars by themselves, with the windows up.

The masks will never fully go away, because so many people are either really stupid, or grossly misinformed.
