Several puzzles in galactic HI studies that were originally discussed by Kerr remain unsolved. The asymmetry in the rotation curve of the inner Galaxy is one of these. It cannot be explained solely as a peculiar motion of the LSR; it is important because small errors in the assumed galactic rotation curve can have tremendous consequences on kinematically derived quantities. Kinematic uncertainties alone make the surface density of HI in some places uncertain by at least a factor of four.
