I have a Boker Trance (with serrations) lashed to my sunvisor on the drivers side with red 550 Paracord. This is in case in an accident I cannot reach the knife in my pocket or the passenger cannot reach a knife in the glove box so there is always one lashed to the sunvisor. If pulled over I wouldn't even worry about it because it's for an emergency not to use on cops.
I also carry flares, a couple flannel shirts (quilted), and jumper cables that I made from welding wire. I bought end clamps from a welding shop along with the wire (I think it's 6 gauge but I'm not sure. It is stranded copper and I then soldiered it to the ends and made my own set. The cables never get stiff and have never failed me. They are good to like -50 degrees F, or 200 degrees F. I could never find a good set of jumpers that I liked so I made my own.
I also carry some screwdrivers, a pair of channel locking pliers, pens, a few liters of water, a sharpening stone, extra towels, a boyscout handbook, 2 flashlights (one large Mag and one Surefire 6P, lock de-icer, 2 Sharpie markers, about 50 feet of 550 Paracord, 3 Bic lighters in a ziplock bag, and a "Light my Fire" fire starter sparker thingy. I think I should be ok should something happen.
Lastly I have a good old CB Radio in my trunk with a 10 foot magnetic antenna should all other ways of communication cease to exist.
I have a bit of OCD.
