Are Cars Lightning-Proof?

Lightning protection: Since the car's outer shell is a large metal enclosure, it forms an equipotential body, so people inside the car don't need to worry about being struck by lightning. Here is relevant information: Faraday cage: The metal shell of the car provides excellent protection for its interior, completely shielding it from changes in external electric fields. Thus, even if the car is struck by lightning, the people inside remain very safe. Lightning damage: Cars can still be damaged by lightning. When a car is struck by lightning, the instantaneous high voltage may damage the electronic components inside, causing electrical equipment to malfunction or, in severe cases, even leading to a fire.
A car can provide some protection during a lightning strike, acting like a large metal box that channels the current to the ground, so people inside are usually not directly hit by lightning. After years of driving, I often remind my family and friends: if it's thundering and raining outside, staying in the car is much safer than standing in the rain. The car's structure forms a Faraday cage, which is a natural protective mechanism. However, be aware that the roof might get struck, causing the paint to melt or tires to burst, and the electronic systems could also get fried. So it's not 100% lightning-proof, and it's best to park in a safe area and wait during a thunderstorm.
