Basically the holes in the cage need to be very small. It has to do with the wave length being smaller than the holes. But the holes in the conducting parts of a Jeep are...

Well, lets just say be careful in the lightning.

There is a wiki on Faraday cages.

I was also thinking about this today as I drove home in a thunderstorm. In a car the electricity will be be conducted around the sheet metal and then arc to the ground. There might be enough metal with the cage and windshield frame to keep you from being directly electrocuted. However, I'll bet the chances of being burned by the super heated gases and/or other arcing around the lighting may be higher in a Jeep.

"The SAFEST location during lightning activity is a large enclosed building, not a picnic shelter or shed. The second safest location is an enclosed metal vehicle, car, truck, van, etc., but NOT a convertible, bike or other topless or soft top vehicle."
