This is sooner than you think - thanks to all of the devices in a car
these days, power transmission and efficiency is becoming an issue
even over those relatively short distances.  IIRC we'll be seeing a
move towards higher-voltage systems in cars (either 42V or 48V, I
can't remember at the moment) within a few years here.
