That's a very good question.
Certainly modern developments in communication and transportation have improved the situation. For example, using telehealth, telemedicine, and real-time video conference linking helps to improve access to care in remote settings. However, in that life threatening situation there is the golden hour, and what's important is that in the community you have health practitioners who have the training, the skills, and the support to be able to save people's lives. And then they're supported by the system, using telehealth, transportation, and so on to transport maybe to a larger centre for care.
I think it's a serious concern in the example you gave, in a community where it's more than a hour and a half to the next centre, to lose that urgent care emergency response capability.
