Alt3, Sad but true on the mindset but clearly they have not been doing it safely (and remembering that evolution will likely come at a further cost in lives).
Sunnywa, interesting concept that would certainly add to the pressure on operators/managers to do the right thing. Additionally, why don't those responsible for issuing EMS contracts simply demand the technology levels. Perhaps lobbying the source of the work will force the standards up of those who genuinely contribute and drive out those who do not.
