My anecdote is remarkably similar. I worked from home for a couple months, then had to mask up for a couple of service calls on essential production lines... There was a massive step function between late February in 2020 and May 2020 on the roads from Michigan to Indiana and back. Coworkers and customers who told me they used to go 79mph in the left lane (because it was unlikely to earn a cheap 2-point ticket instead of 81+ which was a more probable and more expensive 4-point ticket) but now bragged about driving 90+ or hitting "triple digits". It was kind of like talking to a religious fundamentalist who can't understand how unbelievers restrain themselves without the Ten Commandments and threat of torture in the afterlife providing consequences for theft, murder, and adultery. I've never gotten a ticket and had no idea what the penalties were, the legal consequences were never a part of my reason for not driving unsafely.
Speed limits and traffic enforcement had been fully suspended, and people drove however they wanted to. It also felt like there was some griping about being part of the unlucky few who had to risk their lives for the sake of those who got to stay home in safety and comfort with all their necessities delivered.
My brother-in-law's laughing response to my description of my service call drive is etched in my memory. He'd been massively busy delivering pizzas, and after hearing about how I'd had my doors blown off, he said "Welcome to the apocalypse, we drive fast now!"
