This is for EMP - electromagnetic pulse purposes. Remember, EMP's come from a nuclear blast. And they are proximity dependent on their severity. Meaning the closer your are to the blast the more likely it will damage your electronics. Proximity is a factor and size of the blast is a factor. Larger blasts produce larger pulses that are damaging at greater distances. Smaller blasts - less effect ...
And Faraday cages work.
Simple grounding - not so much ... for semiconductors - computer chips.
OH ... and for the older cars - the ignition condensors (they are actually electronic capacitors) would need to be protected from an EMP, also. So having spares stored in a steel box (Faraday cage) would be the thing to do.
