Hi 13on,
Well, I know you pay more than us for gas (petrol) in the UK but our distances are a lot greater than you can imagine; for example, 2 hours on the Santa Monica Freeway from Orange County, doing 60 mph, through LA heading north gets you out of town? Not a chance - LA is still all around you! I was just on a round trip via road down to Lubbock Texas to attend a conference - it worked out to 7,000 plus kms! That would take you from anywhere in the UK to at least Moscow and back.
Because of the relatively high fuel prices out here we have had failure after failure in the airline industry and many trucking firms are teetering on the brink of bankruptcy. If we paid European fuel prices here - forget it - the whole transportaion structure would collapse.
That is why I am trying to get my landy running as efficiently as posssible - because I like travelling by road but its becoming a real luxury.
