They could be thinking ahead so they dont forget it when they get to their destination. They could have forgotten it when they got in the vehicle from their last destination. There may be a kid in the back seat you couldn't see that they are trying to protect (or protect themselves from). I personally don't understand why this is remarkable. In no way are they hurting or affecting you. Why does it matter to you if they mask?
