I have been asked by my family to develop car kits for my teenage nieces and nephews. They are live in small towns in the Midwest. They all have cell phones. Coverage is good but by no means assured. These kits are expected to fit in a small duffel bag in the trunk.

AA LED Flashlight with spare batteries (use energizer primary batteries)
Water - a few bottles of bottled water
44 hour candle (nuwik)
Waterproof matches and lighter
Map & Compass (County & state map)
Duct Tape (small roll)
First Aid Kit
Whistle with lanyard
Blanket (at least fleece, wool would be better)
50' of Paracord (light rope as an alternate)
Gloves, Watch Cap, Spare coat, wool socks, and overshoes

Anything I missed or other comments welcome.
