On October 27, 2021, I rode on two mass transit buses in Phoenix, Arizona. Both drivers were knowingly and willfully violating the federal regulation (42 CFR sec.s 70-71), which requires transit operators to wear masks during the pandemic even when they are situated behind a plexiglass barrier. One of the drivers, whom I had twice before seen not wearing a mask, again had lowered the plexiglass window pane between the driver and customers paying. The first time, I had asked her to put a mask on, given the federal regulation and her proximity to the passengers boarding. Replying as if making an announcement, she said, “If anyone feels unsafe on the bus, they can get off and wait for the next bus.” That prompted a passenger to insult me. The company subsequently backed up the driver's refusal by saying that the federal law doesn't apply to buses in Arizona. It did, so the company violated federal law with impunity.
