The car's metal shell provides strong protection for its occupants against electricity. While many people believe that rubber car tires keep occupants safe, it is actually this metal shell that prevents electrocution. Lightning generally strikes the antenna or roof of a car, the NWS states. However, lightning strikes can create a significant amount of heat and cause fires.
