Sorry, this may seem like a funny thing to write, but it's truly just for the sake of something to ponder, but not of course to interfere with the saving of a desparate person's life.

I had occasion to be sued one time because my neighbor's Doberman jumped over his front yard fence and bit the mailwoman who was putting my mail in my front door slot. Of course, I was extremely upset about being named in the suit (particularly since I picked up her dumped mail, bandaged her hand, and called her supervisor for her), however a lawyer friend of mine said that I had involved myself in the incident, therefore making myself potentially culpable for any fallout from the incident, including being named in the suit by the mailperson who I had helped. My lawyer friend told me I would have been perfectly within my rights to let her bleed all over my front doorstep and do nothing. I imagine the person (or persons) trying to aid a trapped motorist in a burning vehicle also might be similarly culpable if things didn't turn out so good.

Again, just a thought, not necessarily a reason to avoid helping a fellow human in a desparate situation.
