Good point about simply stepping the 42/48V back down to 12V to run low power accessories for backwards compatibility, seems like an obvious thing to do now that I think about it.

Except they're not doing it with 48v; they're doing it with even higher voltages. For example, the Prius uses 200v for the main electrical system.
