I use my car stuff all the time. It is not in a sealed "kit" but spread around in pockets, various compartments and containers. Lots of redundancy in regard to fire-making, which is so important. Knives, too.

Esbit fuel tablets that I keep in a seat pocket came in very handy last week starting a campfire on a rainy day in the mountains. Impressed my friends when I grabbed a couple of those tablets and - viola! - the fire took off.

The extra jackets, gloves, hats, etc. that I keep in the car inevitably are useful for me and friends this time of year when the weather is changing.

I have a bag that goes in the car whenever I drive across the river - I went through that today to reacquaint myself with what's where. I frequently use the flashlights and headlamps so it is important to keep up on the battery supply.

One of the emergency items I keep in multiple places is cash. That will surely come in handy and not just for disaster situations.

Good to use some of this stuff on occasion - practice and replenish.
