How would vehicles survive the EMP of a Nuclear Blast? I'd suspect lots of fired automobile computers. Your not driving anywhere if your computer is not functioning. Would removing the negative battery cable be of any use in protecting your cars electronics??

Nope. The only thing that might protect it is a Faraday cage: a large enclosure made of a metal grid that is well grounded. Try finding one for a car!

Not at all. If you want to put away some sensitive electronics for use after an EMP hit, you need to place them in a proper Faraday cage. If we really do experience EMP damage, I would recommend leaving the "good stuff" in the cage until you are very certain another EMP is not coming. It may be a VERY long time before replacement equipment could be manufactured again. Today's computers are designed and built with yesterday's computers. It's difficult to start from zip.
