The chief accounting officer has nothing to do with that. That'd be the CFO+COO (which Tesla doesn't have)+CEO. CAO is a common position when you have a sprawling, complex supply chain and contractor structure (which Tesla does have).
Yeah, you're right, the CAO has nothing to do with accounting.
I also loved "talk to me when it's engineers!"
Since 2017:
Doug Field, head engineer, gone. Matthew Schwall, director of field performance engineering, gone. Jon Wagner, director of battery engineering, gone. Kurt Kelty, director of battery technology, gone. Chris Lattner, vice president of autopilot software, gone. Satish Jeyachandran, director of hardware engineering, gone. David Nistér, vice president of autopilot vision, gone.
So many people here turning a blind eye, much like they did on Theranos.
