I wonder how many of these fatalities occurred at the crash scene and how many were a result of treatment delays due to overwhelmed/short staffed health care facilities and pandemic protocols? Several emergency centers in my area have had to shut down on weekends due to a lack of on call doctors and patients are being redirected to more distant but larger hospitals. There may be more to these numbers than just bad drivers.
