FWIW and this is anecdotal, but I remember last year when the first big wave of vaccinations rolled out… within the same week while driving home on three different occasions… the cars driving in the opposite direction on the country two-laner were driving in MY LANE. Towards me. Thankfully all three pulled back over to their side of the road in time to avoid a head-on. When we passed each other, two out of the three (both women) had a terrified though baffled look on their faces. The third driver, a man, merely waved a “sorry” hand at me when we passed. At the time when I mentioned this to my wife, we both assumed it was vaccine-related.

One last thing - I live a few blocks from a major hospital. I know it’s not my imagination, but for the past six months or so I’d guess the number of ambulance sirens going past our place has probably increased three-fold. This is primarily during the day, and my assumption is they silence the sirens at night as they approach the hospital, and that’s why we don’t hear them as much after nightfall. Lastly - I’d say the number of Life Flights has doubled during the same period.
