Four OFF the Ground?

[Huw Powell]

We're geniuses!

Wait til we break this idea to the auto manufacturers.  As I see it,
there will be some sort of "key" operating the switch to prevent theft,
and this switch will simultaneously disable the fuel pump and the
ignition coil when it is turned off, via appropriate relays.

Wow.

Sure beats getting out and grounding the coil wire to stop the engine!
