Wow! This discussion reinforces my decision to keep my 20+ year old cars on
the road. 

But, isn't the issue making sure the radio can never provide a path for
current from the "-" terminal on the battery to ground through the radio?

Not necessarily. There is no good reason to bond the radio to the vehicle.
It is, however, necessary to have good RF connection at the antenna between
the coax shield and the body so that it can act as a counterpoise. That
connection could be through a good RF capacitor. In this were done, I see no
reason why powering the radio directly from the battery would be
problematic, or would interfere with that system.

Also, it seems to me that the system you describe is only viable with
electric or hybrid vehicles. There are other significantly greater issues
with installation of a HF radio in these vehicles.
