I don't know the answer yet, but here is the latest brain tease from GlobalSpec:

You overhear a discussion at work where two friends are talking about the safest place to be in a lightning storm. One says to the other: "You're always safe in your car because the rubber tires insulate you from the ground." At this point you feel compelled to interrupt. You point out that yes, you are indeed safe in your car, but the reason has absolutely nothing to do with the tires. What keeps you safe from lightning when in your car?
