Winter Car Kit -- Suggestions Needed

 I am trying to put together a winter car kit.  I have started my kit and have posted what I have in sections.  I am hoping that you readers will leave suggestions and ideas from what you have in your kit.  I have gone through the other kits on instructables but they are not quite what I was looking for.  The closest instructable to what I want is the "Auto Emergency Survival Kit" https://www.instructables.com/id/Auto-Emergency-Survival-Kit/ as it really is a good instructable.  The kit I am trying to put together is not so much survival- fishing gear and fire starters, it is more a kit to stay warm and comfortable if stranded in a blizzard or other situation.  I also always have my cell phone on me with a charger in the car.  Along with a subscription to AAA so a tow truck is available.  But depending on the weather and number of accidents a tow can be a number of hours away.  I know from personal experience.   So please read and leave suggestions on what to add.

So its winter, or will be, and it is cold.  So if the car gets stuck and am waiting for a tow truck the car will cool off.  So to keep warm the engine can be ran or you can use what is in the kit.  In winter I should be wearing a coat and gloves.  To augment this I have purchased chemical heaters for body, hands, and feet.  I purchased knock off Snuggies, because they were on clearance. I purchased a scarf, wool socks and plan on getting wool hats, and gloves.  I also have an emergency candle that can be lit to provide a little heat to the car.  Yes carbon monoxide can build and a window will be cracked if anything is being burned.

For hand tools- Pocket chainsaw, multi-tool, weather radio, 5 in 1 whistle, and a folding shovel.  The 5 in 1 whistle is a whistle, match holder, mirror, compass, and fire striker.  The point of the packet chainsaw is to cut branches to either clear a path or put under the tires for traction.  Also kitty litter for traction. I also plan on adding matches and a lighter.

For food- I have two MREs with heaters. For water- foil water pouches, and a Spoork to eat with.  Because the water pouches will be ice pouches I have included a Sterno type fuel cell and folding Sterno stove.  I will also include something to melt the ice in other a mess kit, pot, or metal cup. The fuel cell is also designed to be burned as a heater.  And yes carbon monoxide is an issue so if it is to be used, then a window will be cracked for fresh air, and with the chemical heaters and blankets I wont be using this as a heater.  

So for hygiene I plan on packing soap, alcohol gel sanitizer and wipes, and a TravelJohn just in case. 

This is a kit for an accident.  So besides the emergency auto kit that is already in the car. A fire extinguisher,  tow rope, first aid kit,  and emergency tent if the car is too destroyed in an accident the tent can be set up for shelter.
