You miss the point blueloo, but how nice to get a bit of anonymous personal abuse in! It may be pleasant to have 50 ambulances standing by watching while you handle a very nondescript mechanical problem, but it is a luxury we cannot afford. Those ambulances would have been better involved doing their run of the mill tasks rather than violently over responding to nothing. Somewhere in the ambulance service, a major decision making process is being handled by someone who does not know what they are doing.
