I only see that in states where you get arrested or fined for not wearing them. I think some people are more afraid of not wearing one due to being roughed up and harassed by politicians. My state doesn’t force them. My county hasn’t mandated them. It’s all voluntary except for a few doctor’s offices. Our four large cities require them but the smaller rural towns like mine don’t. My husband is 82 and puts one on when he leaves the house so that he gets it on right so he’s one of those driving around in his truck with one on.
I only wear mine in crowds but I have for years during virus season. This is the first time I have had to do it all year though. :-) I’m used to them and even I’m getting tired of it. Even with my asthma I only wear it inside stores that are crowded. Both of my doctors that told me to wear one said to wear one around people this year, especially my asthma specialist.
Don’t trucks come with mirrors on the visor? Once I park, I flip down the visor mirror to see if I’m putting the mask on correctly, and that’s just for a few stores where I’ve already dealt with mask Nazis. No need to drive around with the mask on in your own vehicle.
