Not that it would be perfect given your height, but many of the ski shovels work pretty well and fit easily into the trunk of a car. The other thing that surprised me I didn't see was 100' of 1500# rated rope (obviously assuming you have the extra space). I have used that more than a couple times to axle wench myself out of a ditch etc when I drove a Saturn, besides that you never know when it will come in handy. I also carry a set of tea-light candles. They don't take up much space and will generate enough heat to keep you alive in a car even if it drops to -40. It is always nice to be warmer, but the minimums will keep you going especially when you are tight on space.
