Relying on the Red Bus

A substitute for the Roosevelt Island tramway is the red shuttle bus. It typically runs to transport residents from the north end to the south end of the island. According to the Roosevelt Island Operating Corp, it first provided service to residents in 1976 free of charge. in 1990 there was a 10 cent fare and in 1994 it increased to the current fare of 25 cents.
Roosevelt Islanders are relying on one of their last resorts; the red bus along with the Q102 which only goes to astoria, and the F train. The nearest taxi service is in astoria so there is hardly an influx of street cabs on the island.
In the event that the F train wont be running for whatever complications, what will manhattan-bound, island residents do?
