These data suggest that COVID vaccine hesitancy is associated with significant increased risks of a traffic crash. An awareness of these risks might help to encourage more COVID vaccination.

I think this is rather silly. You find a correlation between vaccine hesitancy and reckless driving and that is supposed to make people want to get the vaccine? It’s not like the vaccine makes you a better driver, they even later mention that it is most likely due to the fact that these individuals neglect safety precautions in multiple areas. Getting the vaccine will not change these statistics
