> Sometimes I do this by accident, just forgetting to take it off when I get in the car. Maybe that's common?
I’ve done that. If I plan to make several stops, I might put on my mask at the first stop and then leave it on until I’ve finished my business at the last stop.
Touching the mask could be a potential vector for spreading the infection to surfaces, and could also compromise the seal.
It's typically best to fit it well once and not touch it afterwards if possible.
It's kind of related to touching face or eyes in terms of spreading diseases.
