Well, here on the UK South Coast I pay 94.9p for a litre of petrol (gas!) I have no idea how that translates into dollars per gallon but I have the impression that gas is a lot cheaper in the States than it is here. When I last visited California I recall simply filling the tank without bothering to notice the price. In the UK I limit myself to £20-25 per fill (about half a tank). We used to buy petrol by the gallon until we joined the EU and suddenly became metric. This has the immediate advantage of disguising the true cost of the hike in petrol prices as a litre is only about a quarter of the old gallon. Bring back the gallon I say, petrol was a lot cheaper then.....
