Default 48 volt car elect not going to happen

^^^^^^^^^^^^^^^^^^^^^^^
It is refreshing that SOMEONE seems to know this. However, I have a couple
of reservations about your second sentence. The resistance of the body is
almost entirely in the skin, which is quite high when dry. If, somehow, you
got across some voltage while wet, or perhaps bleeding from an accident, the
resistance could be very much lower. Secondly, the amount of current that
can be lethal depends on the path through the body. The worst would be
across the shoulders, which places the heart in the circuit. The path from
one hand to the other, or from one hand to some lower part of the body could
also be quite dangerous.
