Honestly, Never really thought about saving a car. Even my car.
Because of the news, I always read or saw (Online news ) about some person burning to death in a car or side of highway, through murder or mayhem, car accident, and or drunk driving.
So that's was my initial reason. Saving a poor soul.
Anyways, I'm no expert. So in a related sense, I keep one on my roof rack.
Easy grab & go.
Real basic stuff, flashlight, 2 foot shovel, two first aide kits in wheel well and rear bottom storage compartment.
Oh yeah, I guess I should stick back my electronic air compressor and tire gauge back there. Use them and left in garage.
