Since when is "The public expects us to" an acceptable reason for us to do something? The public as a whole has no knowledge of medicine or what it entails and their expectations should not determine operational procedure.
I think you missed the point.
We Have told them for years that response times mattered.
We Have told them the metric of good EMS is response times.
After a few decades of us spouting this BS. They believe it and expect it.
We are responsible for this.
