Well I get the fuel paid for in one car (the GCHQ company car), and the other is a 60mpg SMART so I don't really notice.

Although...i would like the government to tax high CO2 vehicles more (I don't care about climate change but what else could they tax?) and lower fuel duty. If a protest can make fuel cheaper, but allow for the government to still get the same income (lower duty = billions lost for the gov) then go ahead
