This question was actually in my mind before pandemic while driving back and forth my old job.
There's a good curve at the end of a downhill state highway and if you go straight, there's a pond.
Of course there's a barbed wire fence but I saw a car with its front in the water once.
I thought what would I do if my car goes under water?
What if I can't break glass or belt? I do have hammer/belt cutter thingy but who knows where it'll be when I need it.
So the question, is there something to breathe for a while?
Will a can of air duster help?
Something similar like a small oxygen canister?
