Some day they totally privatize emergency services here. Then the people who are paid up get help until the profit margin drops and the service declares bankruptcy, leaving the government/taxpayers to pick up the tab as usual. Those who aren't paid up will be known as 'Cranicks' and be mocked by talk radio conservatives.
But that won't be happening soon. 
Grey Nomad, what do you think of methane digesters? Any organic waste like kitchen scraps or vegetation off the roadside can in time make fuel, and the 'waste' liquid is good fertilizer. Unlike an aquaponics setup you can probably drive around with a decent size digester on your truck.
