Stupid Petrol manufacturers, selling us petrol with clustered hydrocarbons .
It's just because the goverment (currently flying above us in black helicopters) is conspiring with petrol manufacturers to make cars less efficent, thus making us by more petrol - giving more money for oil companies and more tax for the govt.
I'm currently working on a device that not only de-clusters the hydrocarbons, but polarizes them so they all burn in the same direction. Big savings there as well. And my electric engine that produces more electricity than it consumes is nearly there too!
GT, you should have waved to the UFO - I was actually cruising around in it (3rd abduction this month, bloody aliens - surely there's nothing left for them to see with their probe?).
