A man who called the NYPD for help after a car accident on the FDR Drive was killed as he waited for them — but they never showed, a lawsuit alleges.

Thomas Sauickie Jr., 31, of Hazlet, NJ, was with his wife, Tracie, and young daughter in January 2016 when their car collided with another near East 42nd Street.
