The really crazy ones are alone in their car-driving-with windows rolled up & fully masked.
I think there is something else going on with those types. I live in an area where rush hour has become more like a demolition derby. Over the last few months I have noticed that whenever I am nearly hit, or there is wreckage on the side of the road, it is very likely they are wearing a mask in the car. I doubt the mask is directly related, probably just a marker for some other trait.
As I was getting in my car, at the supermarket the other day, I noticed a lone woman in the car parked next to me with her mask on. She kept lowering her mask to take a sip of her drink. Up and own the make went.
I call them all “mask-tards”.
