I didn't say that it is not CALLED "ground." I said that it has no earth reference, and therefore cannot "leak" to earth through wet tires. Go set a D cell on the wet sidewalk, with its positive button facing down, and no other connection to it. Tell me if it runs down.

The "ground" side (negative or positive) is called that as an easy way to differentiate it from "hot." It could just as easily be called "return."

(The British refer to it as "earth" but they call everything that is grounded "earth," so that's irrelevant.)
