You can also get struck thru the window of a hard top car. I live in the lightening capital of the world - don't worry. I drive my car in heat lightening storms all the time with the top down (no rain). There is a lot of stuff around you that is way taller & more conductive than your car. You are probably more likely to have lightening strike a tree & make it fall on the roof of your car than actually get struck driving along. Don't worry about the lightening - just have a good time!!
