1) In my opinion 
2) Correct - but I'll bet if you're stuck behind them for 4 hours you'd change your mind
3) No fuel protest in this country ever makes a blind bit of difference - I remember travelling from Perth to Glasgow every day for a week down the A9 at 30mph - it was curiously relaxing, but ultimately futile
4) True, but if you're going round in circles whats the point of the journey?
my solution? start targetting petrol companies at random - this month, no one buy any Shell for example, the month after Esso, then Tesco for a month, then Asda and so on (we all need fuel so having days you don't buy any is pointless)....also make it completely random and picket the targeted petrol stations - i'd give it 3 months before the gov't were begged by the oil companies to reduce tax 
direct action, not parping about on hogs 
Your solution, BJ, carries some merit -- but the little protests help get the word out and highlight the problems ... like a spark becoming a fire.
Regarding 3) We need to get better at it, look on this as practice 
And 4) ....... Life is a circle, Grasshopper 
we should be as militant as the french - they'll grind the country to a standstill and won't give in til their demands are met

I know the bikers have the right idea - but it was early morning and i heard it on the radio and i was cranky and thought - if you're going to protest lets do it massively and unstoppably

err....grasshopper
