Ok, why should a fly car require special training? It is just a non-transport vehicle used by an EMS provider.
Currently I have the following, which serve the following purpose in real life.
Medic 18: ALS Fly Car, assists surrounding BLS Ambulances by providing advanced care to serious patients.
Medic 20: ALS Fly Car, assists surrounding BLS Ambulances by providing advanced care to serious patients.
Medic 28: ALS Fly Car, assists surrounding BLS Ambulances by providing advanced care to serious patients.
Defib 29: BLS Fly Car, first responder care when the Ambulances are busy.
Medic 30: Same as Medics 18, 20, and 28
Medic 31: Same as Medics 18, 20, 28, and 30
Medic 32: Same as Medics 18, 20, 28, 30, and 31
Medic 36: Same as Medics 18, 20, 28, 30, 31, and 32
Defib 37: Same as Defib 29
Defib 39: Same as Defibs 29 and 37.
If you want them to add special training for a fly car which is basically the same as an ambulance, then we would need special training for ambulances as well.
