>> We scale it down depending on income and type of event. We're not massive sticklers about it.

That touches on another very american problem. The injured person now does not know how much the tansport/treatment will cost. And the only persons on the ground cannot quote a price. If they say yes they enter into that zone of having another random health care bill comming in the mail. Is it 900, or 9000? Will my insurance cover this? Is this outside my deductable? ... this is math that no person should have to do while bleeding beside a highway.
