This is another one we should consolidate, _nidec_scm_group_b is the same thing as Bosch, needs a round of generator cleanup. Same as KINEMATICS, just got done doing a bunch of generator cleanup and want to avoid adding new drift/rot where every car's version of that message ends up being slightly different. I'll do the cleanup myself at some point if you don't have time.

These seem to be a differential pair to each other

I can just remove this. I don't have any idea what it may be. Can add back in after further clean up
