A direct electrical discharge from the atmosphere to a vehicle presents a potentially dangerous, yet often survivable, scenario. The metal shell of a typical automobile acts as a Faraday cage, conducting the electricity around the occupants and discharging it into the ground. This protective effect minimizes the risk of serious injury inside the vehicle.
The effectiveness of a vehicle’s Faraday cage relies on the integrity of its metal structure. Complete enclosure, including a metal roof and sides, is crucial for directing the electrical current safely. While tire composition offers some resistance, the primary path to ground is through the vehicle’s frame and suspension. Historically, instances of this phenomenon have demonstrated varying degrees of damage, ranging from minor electrical system malfunctions to tire explosions and paint damage. However, fatalities are rare when occupants remain inside the vehicle.
