Tire chains (illegal to use in mine country) and come alongs (with chains, treestrap, etc) are a bit too big for mine trunk. I drive a Hyundai Getz, so there is not much space in the back.

I do have a towing rope in the car(and jumper cables, tools, jack, tape, steel wire, ziptie's, powerflares, LED panel, reflective vest, flashlights, etc...), but somehow i always get stuck in a situation where towing is not a option.

I know the snow claw, but that thing is useless in anything but snow and you does not have the reach to get under your car. (and is not nearly as good as a snow shovel in the back country). I could barely reach the sand under mine axle with mine trifold.
