Killgar, you'r posts are almost exactly what both my father and our scout master told us as boys. That when you walk out the front door in the morning, you never know what will happen before you make it home again.
Like in January of 1991, I was driving with our 18 year old daughter Jessica, to the Toyota dealer in Frederick Maryland to pick up a couple year old corolla for her to use to go off to college with. An old Datsun B210 blew past us at a high rate of speed on RT 26 approaching the left hand curve under I15. VERY sharp 90 degree curve. She didn't make it. Spun three times, over turned and rolled and ended up against the guard rail. We pull over and go running and smoke is already coming from the engine compartment, and I look in and the battery has broken loose and is up agains the old greasy engine block shorting out. Black greasy smoke and lots of it.
Worst all is we hear a baby screaming, and I crawl in the upside down car, theres a infant in a car seat in the front passenger seat. Okay, push seat belt release and car seat with kid falls on me, and I push the whole thing out to Jess, and she gets the kid the other side of the guard rail a bit away. Driver is a whole other problem.
A very obese young lady is wildly thrashing around screaming hysterically, and while I am trying to push her seat belt release she actually backhands me in the nose a good one. I'm pushing with both thumbs, and its just not releasing. By this time the car is full of greasy choking smoke, an I dig out my pocket knife, an old well used Buck 301 stockman, and pull open the sheep foot blade. Sheepfoot blade because this lady is thrashing around so wildly I don't want anything pointy around her or me. Once the seat belt is cut she falls on her head and I get the hell out of there. By this time the fire department and police are arriving as this was all on the highway almost in downtown Frederick. We give a statement to the cops and leave. I go to a Roy Rogers for a coke to gargle with to get the oil taste out of my throat.
Moral of this; I didn't plan on playing rescue guy that morning. I was just driving to the Toyota dealer where we had wrangled a deal on a couple year old car for Jessica. But this happened right in front of us and there wasn't anyone else. It was early on a cold winter morning and there wasn't a lot of people lining up taking numbers for the job. Just me and Jess.
Everyone should be carrying something! Any little bit of sharp steel will do in a pinch as long as its sharp. Even a little SAK classic will cut a seat belt if need be. That old lady that choked to death in that Boston shopping mall didn't need to die like that. If just one person had a little knife, even the SAK classic, her scarf could have been cut loose from the escalator steps where she feel, to free her. Even a box cutter or a razor single edge razor blade in a wallet! But nobody had anything. That was a crime.
Carry SOMETHING! Even a Spyderco grasshopper or a Buck mini buck. And make sure its sharp.
It's good that there were people there that day (you and your daughter) who had both the courage, and the will to act, and had the right tool for the job.

I've seen stories on tv about people trapped in smoking or burning cars with people trying to help shouting "DOES ANYBODY HAVE A KNIFE?!". In one incident it was the first responders asking.
We had an incident here in San Diego recently where an active duty Marine used a knife to cut a baby from a car before it burst into flames. Technically, he used the strap cutter that was built into his folder to cut the kid out, but still a knife. Plenty of online news reports about it if anyone is interested.
Off topic- Your story reminds me of what I've heard from first responders about how dangerous, and even combative the people can be that they are trying to save. Whether it's shock/panic, brain injury, drugs/alcohol or a combination, it can be downright hazardous trying to save someone. It's living proof that "no good deed goes unpunished" when you're pulling someone from a burning car that's about to explode and the person is punching you in the face the whole time
