I don't think that patients should be tranported to hospital Before HART or other Rescue Units needed have arrived!
Missions such as :- Injured person Stuck on high voltage mast.
Parachutist stuck in tree.
Person Under Tree.
Person Under Train.
Injured Peson Central Wound.
etc ect....
These Missions should wait for ALL Units to arrive before treating Patients otherwise there is NO NEED FOR SPECIAL UNITS to attend, because there is NO PATIENT LEFT to rescue!!
The Lifeboat and Coastguard missions do this so why not others?
