That's a cool maks.
"Not even for a joke", but for the video it's okay.
You are right that if it's in the car, it's game over.
I ride a crowded subway every day to work and haven't got it. I wear a mask on there. But I'm sure you don't just have random strangers in your car (you said alone).
I think if you are going through a drive-thru, or get pulled over by the cops, it's alright. I don't even wear it when walking down the street unless I'm headed into a crowded area.
