gentle encouragement to be antisocial
I am suggesting that "prior plans" and "tradition" are insufficient justification for making unwise travel choices during hazardous weather. Blizzards, icing and snow accumulations do not cause highway accidents. Severe weather is
associated with an increase in highway accidents, because drivers (especially middle-aged, male drivers) pretend that the weather and road conditions are not of concern, when choosing to fulfil their travel plans.

EDIT: I originally posted the weather map because seeing nearly the entire country splattered in colors, like a pizza or exploded stromboli, is truly unusual. Colors always indicate some sort of "watch," "warning," or "alert."
