At the end of Friday’s East Hampton Village Board meeting, Mayor Paul F. Rickenbach Jr. came down on cycling groups who fail to yield to motorists or pedestrians. Mayor Rickenbach also admonished groups of runners who occupy more than their share of roadways. “Be civil, be cognizant,” the mayor said, adding that “some bicyclists and joggers are ignoring New York traffic law, which is not the way to behave.”
