I have thought about this some more and wonder if the underlying problem is not necessarily that you need more ambulances to do the real job (helping people who have a medical emergency and getting them to hospital) but that you need a more effective (i.e human and not pre-determined script based) triage system - so you spend your time doing your real job. This is a point you have made loads of times and I think is behind your inablity to help patients like this man in a reasonable timeframe. My take is that we have become so risk adverse as a society that we are actually taking much larger long term risks because we are unable to face up to the short term ones.
