So do I need to manually start a new bus when running as root? If so,
how do I go about this?

I explained my reason in a prior email. I'll re-post excerpts of it.

------------------------------------------------------------------------------------
My application, a text editor, can spawn multiple instances of itself.
I use D-Bus to ensure all instances use the same process. I also use
D-Bus for inter-instance communication. For example, via D-Bus I can
show users all open documents, and allow them to manipulate the
documents (e.g close a specific document, focus a specific document
window, close all running instances, switch quickly between documents etc).
Perhaps my D-Bus usage is unconventional and uncommon.
