Same things go in my pockets anytime I walk out the door. Wallet, comb, Fisher Space Pen (compact bullet type), Burt's Bees chapstick, Rambler SAK, keychain with tweezers, P-38 and house keys and mailbox key. I keep my car key separate. My smartphone, and there is a charger in the car always. I also carry a flashlight, normally a AAA Olight i3 and one spare battery in a county comm delrin holder. A little pocket change and a wristwatch.

If I am going to a real knarly area (seldom), I take my .40 cal. pistol and a spare mag.

My car, a Jeep, normally has a fixed blade Mora knife, a SAK Farmer knife, a folding e-tool shovel, jumper cables, fix-a-flat and the usual spare tire and jack. On road trips I add a compressor, 12v and some basic hand tools. Also always have a pen and a flashlight in the car. Winter time, I add a snow shovel, a sleeping bag and some warm boots and clothes. That is pretty much all I can think of.
