This seems to be the simplest, most practical jamming system I've yet
heard of. Anyone have any suggestion for how to build a switch I could
safely operate from the dashboard to shunt a spark-plug wire through
an antenna (it need not be the radio antenna). Perhaps a loop of
copper braid attached to the inside of the plastic grille would do?

Any solenoid switches out there that wouldn't weld shut when switching
spark-plug voltages and currents?
