What is the Principle of a Faraday Cage in Automobiles?

[CoreyRose]

Electronic components in cars and aircraft utilize Faraday cages to protect signals from interference. Here is the relevant introduction: Faraday Cage: More specifically, a double-stitched Faraday bag, commonly used in digital forensics to prevent remote erasure and tampering of criminal digital evidence. The U.S. and NATO's Tempest standards, as well as similar standards in other countries, include Faraday cages as part of broader efforts to provide emission security for computers. Warning Systems: Sensitive components may include wireless door locks, navigation/GPS systems, and lane departure warning systems. Faraday cages and shields are also critical for vehicle infotainment systems (radio, Wi-Fi, and GPS display units), which can be designed to function as critical circuits in emergency situations.
