Disasters are known to happen at night. Cars can drive on terrain we just usually don't because it's seen as impolite. This isn't about transportation (or the width of your tires) it's about having a layer of security, some storage for more than what you can physically carry, a place to sleep off the ground, and shelter from the weather. Plus, you know, a radio.
Well, aside from the physical security aspect, sure. There are more than other people to be afraid of. Animals are severely annoying if you're out in the wilderness with something like food.
