I agree modular kits have things for and against them, when your trying to get a small kit they do cause a lot of wasted space, but its great when you can just open it up and grab the nice colour coded easily labeled pouch for whatever has just come up.

Whats the score with the Surefires? I've seen them a few times and heard various positives and negatives about them. The big negative I've heard is that they drain batteries really quick and as such aren't great for if your stuck by the roadside or something where you need light for a long time. But then again I've never actually owned one.

I keep my car in a garage and the temperature doesn't fluctuate too much where I live, but I'll have a double check over everything and make sure nothing is going to be too at risk.

Good ideas for additions. I actually have a neck immobilization brace already (its down as "1 Adjustable Extrication Collar" but thats probably not too clear. Its a pretty good one with 16 different size settings and it stores flat which is most useful). What are Israeli Dressings? Not come accross them before, I'll have to go look them up.

Oh and I do have some other equipment in my car. Including a fire extinguisher, an umbrella, a good pair of binoculars, change of clothes, waterproof jacket, and a few tools. MIght be worth putting in a "proper" survival kit as well, good point.
