I used to take a boat to the East side of Manhattan on 34th St and tried the bus to get cross town. It was always faster just to walk. The only time I took the bus after a while was if it was monsoon rain.
The bus system is the last hope of the handicapped and with the busses kneeling at every other stop, you can forget about them as meaningful transit.
I explained this story to co-workers who were insisting we take a bus to a client meeting and they said I was crazy...a half hour later we moved about six blocks on the bus before they gave in and we just walked.
