Nah. Good joke, but don’t do that. Here’s why:

1. You’d first have to wrap the vehicle in a good dielectric (insulating material) and THEN cover the vehicle with foil. And do that two more times before you could sufficiently attenuate the energy of the pulse.
2. You’d have to accomplish the near- impossible task of ensuring no gaps in the coverage top, sides AND bottom. Net: that’s impossible.
3. Not necessary if you follow the prior instructions. 😉

A real Faraday cage would be 3/16” steel with xrayed and die-tested welds, and with a very high tech type of seal for the door. It’s much easier to just prep the vehicle itself.

A poor man’s Farady cage for a CME and maybe even HEMP involves nesting. I’ll use the example of a portable ham radio.
1. Remove the battery(s) and wrap those and the radio individually in dry kraft paper (like butchers paper).
1.1 completely seal each of those with aluminum foil wrapping.
1.2 REPEAT two more times so the radio and each battery has 3 complete layers of paper-foil.
1.3 do the same for the charger.
2. Line a 2-5 gallon metal can with paper and bubble wrap and place the radio, batteries and charger bundles inside. The goal is to ensure an air gap between the can and any of the bundles. Cover with paper and bubble wrap and close the lid.
3. Seal all gaps, welds and penetrations with the aluminum tape HVAC tech use. No gaps = good. Any gaps = failure.
4. Put the can in a location where like the car you can ground it to earth. If your dwelling situation prevents this, at least sit the can on the bare concrete of a garage, basement or utility closet.

A typical metal garbage can let you store numerous items safely. Triple nesting, air gapping and judicious sealing are your KPIs.

FYI you can even fit a small camping generator into metal garbage can per the above. Nesting rules apply.

BUT: if we get hit nationally with a nuclear HEMP, we are all hosed. 13th century life without the 13th century skills and tools.

A solar CME is ‘survivable.’ IMHO.
