If a friend of yours has fallen through ice into a frozen body of water and you would like to save them, lie down on the ice and crawl out to them, DO NOT walk out to them standing up. This maximizes your surface area and lessens the likelyhood that you will fall through the ice as well, getting you both f@#ked.

just turn the car off, unless you have one of those stupid "futuristic" cars with Engine Start/Stop button that cannot be used while vehicle is moving
btw IF u find urself in such a situation use a breathing technique l(like wim hof) to fill ur blood with oxygen, if u do it properly even w/o training u can hold ur breath for minutes. when u have enough oxygen in ur blood the urge to breath is gone and u can be quite relaxed and save even more time through that.
