My Get Home Bag🎒: What changes are needed?

This bag is going to stay in my car most likely, I take a lot of long drives between New Mexico and Texas.

Some items unlisted that I have ordered:

Maps Gloves Orange bandana Radio MRE peanut butter packets

Trying to decide on the best option for boiling water?

I have a jet boil but I would almost rather carry just a small pot and a Nalgene. I also have a hydroflask.

Also good shelter options? I own an eno hammock but need a good tarp.

Usually try to keep good shoes in my car as well.

If you have any advice please feel free to share.
