Are you sure about the frequency and speed? SBST drivers don't
really road-hog nowadays. Not only that, frequency-wise...
334 can have 3 min frequency during peak hour. Not visible on svcs
like 190. 190 is a very good service, but SMRT doesn't seem to be
improving its frequency. Did you notice the never-ending queues?
Not only that, it is understandable you feel this way. Perhaps it
is the place where you live that could be the reason, where SMRT is
predominant. But I assure you SBST frequencies are better. No doubt
about that...
