Why is gasoline so much more in the UK?

I was visiting in England in 03 and Petrol was out of sight at that time. There are 3 reasons for this. First- The whole British Isles will fit nicely into lake Ontario so there's really no place to go in England and secondly-The rail service is second to none. You can go anyplace by train and its inexpensive. Thirdly- because driving is a Luxery its taxed to the Hilt. There are many familys who don't own a car, but even so the Roads are jammed with motor-cars.All the more reason to tax drivers.

I'm not sure why gas would cost so much in the UK, but just a thought here; I know that one U.S. dollar is worth half a British pound, so $7 U.S. dollars would be like 3.50 in British pounds...
