I dont think companies like Shell and mobil making record breaking profits helps peoples moods either.
65% (approx) of the cost per litre goes into the governments coffers.
I dont think there is anything we can do in reality, being typically British we just lay down and take it - and then just bitch about it, crying how crap our government is and how we always get shafted....even a change of government wouldnt change that - they are always in it for themselves.
To be honest, theres that may protests going on in Trafalgar Square every day, with everything from Free Tibet to this that and the other, I dont think anyone would notice.
Going down the route of the truckers (not literally in planes of course) trying to cause disruption to make people take notice will only succeed in pi55ing people off
