Maybe playing devil's advocate here, but if it was the ambulance's fault then the ambulance company's insurance should be paying for all of the medical bills, including the ambulance ride. And the bill for the ambulance ride pays the EMS workers salaries and the vehicle maintenance.
The amount of profiteering in the medical industry is obscene, but I'm not sure this is an example of it...
Meanwhile in Russia(and pretty much rest of Europe): citizems get full healthcare and even foreigners get some of it. For free.
This is what happens if any foreigner for example breaks bone in Russia:
Emergency, including emergency specialized, medical care is provided to foreign citizens in case of sickness, accident, trauma, poisining and other cases requireing emergency treatment. Such medical treatment provided by state and municipal healthcare organizations is free of charge.
