There’s a meaningful difference between “it was 20-30m for them to arrive” and the previous post’s “hours.” Almost an order of magnitude’s difference.

And that’s a medically meaningful difference. 20m response time, 45m to the hospital, you’re still in the time window for critical therapies for heart attacks and strokes. Several hours response time, you’re not. I mean to say, I’m not nitpicking: the difference between your scenario and what the previous poster asserts is large and medically meaningful.
