Nice list and it covers a lot of contingencies. By comparison I am light on shelter/foodstuffs in my normal kit but I get pretty close to this when packing for travel (i.e. not commuting to work).
I didn't see the following which are part of my basic car kit (Maybe I missed them).
- Good, Heavy Duty Jumper cables
- Good tow rope / chains
- Spare Fuses for my car (right type/size)
- Brake Fluid and Transmission Fluid
- Zip Ties (how did we ever do with out these)
- Some basic automotive tools
My basic car tool kit may be a bit excessive (grandpa owned a garage/towing business) but here are some additional things that I carry.
- 12V Test ligt
- Fuse Tester
- Code reader for my car (actually any OBDII)
- about 6-8 screwdrivers (phillips/standard varying sizes)
- offset screwdriver
- Set of combo wrenches from 1/8 to 1" and Metric Equivalent
- adjustable wrenches (one big and one small)
- Standard and Needle Nose Vice Grips
- Standard and Needle Nose Pliers
- Forceps (straight and curved Kelley style)
- Standard and Metric Allen Wrenches
- Spark Detector
- spark plug gapper
- Tape (Duct, electrical, Muffler, tail light)
- Hammer
- 12V Halogen spot light
- Hydraulic Jack (hate those things that come with the car)
This is just for my regular around town driving, I add more for "traveling". The wife just shakes her head and makes me pack the car.
