New York City's slowest and least reliable bus routes have been revealed in rulings by the New York Public Interest Research Group.

NYPIRG says the slowest bus in all five boroughs is the M102, which covers Harlem and the East Village areas, going at only 4.5 mph.

The award for most unreliable, or Most Bunched Bus Routes, went to Brooklyn's B12, which covers the Lefferts Gardens and East New York neighborhoods.
