Yayin, unfortunately adults cannot be trusted to use good judgement. In previous bad snowstorms numerous cars were stranded on highways. This had several bad outcomes: drivers/passenger lives were at risk, rescue workers were forced to put their lives at risk and, by blocking roads and impeding snowplows, made the job of sno clearance that much harder.
In addition, you do know that the Metropolitan Transportation Authority ( which operates the subways, busses, Long Island railroad and Metro north Railroad ) is controlled by Gov Cuomo and the MTA chairman, not Di Blasio. They made the decision to shut them down.
I’m no fan of Di Blasio and there enough issues to legitimately criticize him for without making up new ones.
