I rememeber Sierra comming out with a Driving tutorial some time ago that you could even update with the specific highway laws of each state. You may want to look into buying that, or downloading the Abandonware version if the program isn\'t being sold anymore.
The best way to learn, is to just do it. Find a few buddies who know how to drive and go out to the country backroads and have them teach you. It won\'t help when answering questions like "You should signal ____ feet before making a turn", but couldn\'t hurt either.
