They probably will. Vehicles will soon be made to run at 48 Volts or so.
It's better for the computers, but will probably let a lot of smoke out if
you are not careful.

Re: Battery Connected Backwards
As they say, nothing is foolproof - fools are just too damned
ingenius! I once had a flight line mechanic who shaved down the (big)
rubber connector from an MA3 APU so he could get the plug i to start
the a/c. Problem was, he insisted on plugging it in backwards - on a
system that provided 800 amps @ 24 volts to the starter and internal
nicad batteries. That reverse connection flipped the APU upside down
on the ramp.
Problem with the automotive systems is that the connectores don't have
to fit to do the damage. The posts (even the side posts) are exposed
so that it's easy to simply touch the cables to te posts and get
current - like Bill said, that's all it takes to blow the alternator.

Re: Battery Connected Backwards
48 volts is NOT better for the computers - the most recent laptop
processors are running at 1.8-19. volts for power reasons. It IS
better for motors and power distribution as you can 1. use smaller
wires for both cost and weight advantages (as well as handling and
installation) and 2. reduce the power loss in the wiring because power
is proportional to the square of the voltage.
