My heart says go for it - my brain says otherwise.
A broke country, no money, government have a policy in place for fuel to raise funds, remove some of that and the money comes from somewhere else, income tax maybe, so lets put that up they say. Or it could be VAT, or they will put up VED, or it could be a tax on food, the list goes on but ultimately you will pay for any money saved on fuel, you just wont realise it.
I remember the cheers and the 'up yours' to banks when charges for letters sent to customers could no longer be charged at £15, shortly afterwards current accounts were suddenly £5 per month, the banks were not out of pocket, they simply recouped it in a different way, they had to otherwise their business model would collapse along with your savings.
Oh the futility of it all
