Unless you drive some Ghetto cruiser like a '88 Buick, or you drive like a madman, there won't be any reason for the cops to search you. Just have it handy in a bag, and if you get pulled over, hide it... the cop will probably just give you a ticket and move on. Shit, I have been arrested and i had weed in my car, but they didn't search my car at all! lol. All they had to do was look in the side compartment.
