Honestly, for 'emergency' things a taxi service is a good complement. Busses are good at regular routes between frequent routes/hubs, not for 'I need point to point immediatly now'.
The goal should be more to cover peoples normal transit needs. So plenty of routes with stops very near most people's homes and destinations, and a high enough frequency at most hours of the day and night to not cause too much waiting frustration.
