I followed road traffic safety since 2020 closely (and have submitted and posted about it here) and traffic fatalities is slowly coming down since 2020. My hypothesis about it was that the empty roads in 2020 caused drivers to degenerate in terms of road manners. For example, deaths per mile actually increased in 2020 despite people driving fewer miles which suggests people drove less safely.
On the other hand this article says there was a 65% increase in significant incidents from the year prior to Sept. 30. So I think these are two different issues.
