So let me get this right... The price of fuel is costing the NHS -like the other emergency services and the rest of us- far more each year, so their reaction to this is to have ambulances "roam around in a half mile radius". In a low gear in city traffic. Using fuel and adding to the pollution. (Is this some kind of 'patient creation scheme' to cause asthmatics to have attacks due to fumes?) Hmmmn. Sound a bit of a strange cure for rising fuel prices. I thought the days of driving around for the hell of it went out with the fuel crisis in the '70's? I wonder if and Gordon Boris know their ambulances are going to be adding to the city's pollution levels and carbon emissions like this? Might be a thought to ask...
