Here is Massachusetts we experience weather similar to southern Florida during late June, July, and August: temps in the mid 90's, extremly humidity and severe thunderstorms in late afternoon.
These storms really scare the crap out of me. They always happen after I have taken my lunch so I can't just stop for lunch usually.
Also, I feel extremly vulnerable in the package car. Its one BIG METAL BOX for heavens sake and I get scared.
I know your own car is a safe place, but not the UPS truck.
Is there a physicist around here? From what I understand you are safe in your car WITH THE WINDOWS ROLLED-not because of the rubber tires, this is a myth-but because the car becomes a solonoid

(or something like a long, thin, closed piece of metal). Anyone with a science background confirm this?
The package car doesn't fit this description and that really worries me. To me, its just one huge piece of metal just waiting to be struck!
I don't care, if I feel my life is in danger I will seek shelter and message the center on my case!
