what it didn't have space to say, I'll add here... who the hell are you protecting yourself from in the car alone with a mask on?
What are you afraid is going to attack you, in your car, alone, that a mask will protect you from? Air? If something is going to get you in the air, in your car, through the cabin air filter... that mask isn't going to stop it, as you'll have what ever you're afraid of, all over your clothes, skin, etc.
Am I wrong? Did I miss the important public service announcement where the govt told everyone why you need a mask on, in your car, alone?
