To function as a Faraday cage or shield for a given wavelength of electromagnetic radiation, any holes in it need to be smaller than the wavelength of the electromagnetic radiation of interest, and the cage thicker ( skin effect) than the wavelength. That would imply autos would work poorly to shield against EMP from a nuclear device.

What are the odds an emp attack will be 'weapon of choice' for Putin? Your guess... And how prepared are we?
