The real benefits for a B44+ going to KCC would be people along Empire Blvd, Church Ave, Newkirk/Foster/Junction and points towards Sheepshead. The real KCC bus is the B49. There’s no need for a Williamsburg bound bus going to KCC even when school in session.
HOWEVER, should a B44 go to KCC let it be the SBS versus the local. Also, B49 needs to be left alone. No need for redundancy service for Coney Island via Bed-Stuy. You already have the B74, B82, B68, B36 and to an extent B1 and B4.
Throw the whole Brooklyn re-design in the garbage.
