I would be careful with these judgements.  There are medical conditions (sensitivity to mold) where people are recommended to wear n95 masks in certain situations. You'd see them occasionally pre covid.  I keep them on board for when I'm working in my engine room where all kinds of questionable shit likes to grow(I just did that 2 hours ago without a mask like a dipshit, sigh).  Yes,  post covid 99% of these people absolute twats but you may be incorrectly judging someone, like my grandmother.

Just sayin 

 no there isnt. Nobody was was driving alone in cars with windows up and masks on before 2020. You never saw it because nobody did it. I have never once seen a person IRL with a mask on until the word lost its mind in 2020.
