This is a very timely post and made me re-check what I'm carrying in vehicles.
Can you be TOO safe?
In my 20+ years of off-roading and 4-wheeling in the outback and rock crawling trails of Arizona, California, New Mexico, Utah, and Sonora Mexico, my 4x4 pickup truck always carried a long list of spare parts and safety equipment.
Here in Arizona the summer temps can almost destroy much of the contents of a basic First Aid Kit in a few hot summers. I re-checked my auto and home First Aid kits. To both my auto kits and my home kits, I've added a tourniquet

and a chest wound seal

In my passenger cars I carry water, a jacket, emergency medications, pocket knife, little flashlight, Leatherman multi-tool, blankets, towel, leather gloves, and jumper cables.. I just ordered a fire extinguisher that I can mount in the trunk.

I do carry, nearly every time I leave the house, a Kirshaw OTF Livewire.
Anyone who saves the life, or attempts to save the life, of another will always be an unquestioned, noncontroversial hero in my book.
