Why doesn't lightning affect people in a car?

Answer 1

There's a special effect in a hollow sphere of metal, called a 'Faraday Sphere', where there isn't any electricity in a sphere. Faraday, the guy who came up with rules on the electricity that we now use today, first found out that a hollow sphere has no electricity in it.

So in a storm you should be safe in a closed car as long as it is spherical...
