OK, this is getting fairly ridiculous. Air medical transport is a relatively small field. If you have a crash, it's dramatic and has the potential to skew small ns. I could put the same spin on the danger of Ned the paramedic flooring it 60 mph down residential streets for a 104 year old in cardiac arrest.
Also, not all helicopter services are the same. You would have to compare type of helicopter, number of pilots, type of area (I would guess that doing mountain rescue would increase danger).
Lastly, the helicopter does not just give "a fast ride" to the trauma center. Critical care starts in the field. Airways are secured with paralytics, chest tubes are placed, trauma lines are placed, blood is given, I can do a FAST while we're starting resuscitation.
Can a system like this be abused? Frequently. Can this system make a difference in select critical patients? I don't have any doubt.
