When I'm getting out of the car, I automatically reach for my mask to put on. Whether I'm going to work, the store, wherever, I'm going to need it on, so I always have one stashed in my shirt pocket. A couple of times after running to the store for something, I've gotten home and upon getting out of the car, I reach for my mask only to realize that it's already on. That, and I'm home now, so I don't actually need to put it on, but hey, I spend half my life on autopilot these days anyway. But what it does mean is that I've driven around a few times alone in the car with a mask on, simply because I didn't realize it was on. No biggie. If anything, maybe even a good thing. If people are so used to wearing masks that they wear them when they don't even have to, that's good.
