I just paid the MOST that I have EVER paid to fill my car this week, and it doesn't overly thrill me. However...
Playing devil's advocate
I'm not sure that petrol prices ARE too high so long as so much of the population can still afford to fill these gigantic 4WD trucks and things that they do not need for cruising around the city and picking up their kids from school... I'm all for them if they're being used in the country or mountains or something actually requiring these types of all terrain vehicles, but just for the sake of being taller on the roads than other people is ridiculous. A huge 4WD without a speck of dust or that has never seen a country road is a waste.
I'd prefer to pay a premium on my fuel and not have to struggle to see around the car that is three times larger than what I drive, or not be able to park at the shopping center because the driver of one of these overly large vehicles doesn't know how to drive it and needs to take up 2 car parks because they can't straighten up. I'm tired of having to be overly cautious because they either have a massive blind spot or consider themselves large enough to own the road that they don't need to look before changing lanes.
Not sure it's such a problem in the UK... Here in Australia, we're gradually turning into a mini Texas!! Glad I moved away from Melbourne before the Hummer dealership opened there - I always see them on the roads now when visiting friends and family. Then again, I moved somewhere small enough that I can generally just use a bicycle to get around
