I keep a small stash of $1 bills in my BOB in the car. As for the driver's license/bank card, if you don't need them with you have you thought about keeping them in your bag in the car? When you leave your vehicle just put them in your bag, until you come back out again. If I am going to a store I put my cash money and CCW permit in my pocket (I don't wear anything without pockets, skirts, suits and dresses included) That way if my purse is stolen, I don't lose those items. THe driver's license is much easier to replace than the permit, and I can use the permit as picture identification, and I really don't want a thief to get all my cash if they steal my wallet!
Just a thought.
