I don't know if this is relevant, but in my '66B, the ignition switch is
so loosely constructed, and/or the key is so crudely cut (one simple
notch), that I can easily remove the key without turning off the
ignition. In fact it once fell out on the floor while driving. Sometimes
I have caught myself pulling the key out before I have turned it all the
way to the Off position, leaving the switch in the Accessory position,
only to notice seconds later when the fuel pump gave a kick.
But I imagine the '78 ignition switch is considerably more complex.
