Most of the racer supply houses have main electrical switches that can
take all the power from the vehicle.  They are required on racecars.   Lots
are activated with a pull handle that is wired to be accessable outside the
vehicle in the event of a crash where the driver might be unconscious,
etc....The track crew can see this red handle clearly marked, jerk it, and
all the power is cut...

   Many of these switches have a removable "key"..too.     It would be a
simple task to install one near the passenger seat, into the main battery
area....with the wire pull for use to the outside of a race car, you could
also have a mechanical 'remote' switch.....

   They even have some that have a feature to save your
alternator...whatever that means....
