What non automotive accessories do you carry in your car?

Well to be fair, lolol, you cannot kill zombies with guns. Everybody knows that!!

Seems like whatever I carry, it's either a lot of stuff I never need, or I never have WHAT I need

Water, soap, paper towels, NONE OF WHICH can you buy right now

If possible a portable "bucket toilet"
Some sort of emergency food. On day trips I often take a lunch in a cooler, with half ice filled water bottes

Camera, gun or two or three.........................LOL

Some tools, mostly for mental propping, I can't fix this new crap on the road, anyhow lol

Depending on how far, a sleeping bag
