Holy gas tanks Batman!
My Acura has a 16 gal tank but it probably had about 4 gal left in it when I filled it at Costco which has pretty much the cheapest gas around here. Costco is a membership chain that you can buy usually bulk type items for a bit cheaper. Not always bulk though and definitely not always cheaper but they have an awesome policy for taking things back when they die. Hey, they even have cameras! I would probably have a difficult time trying to convert myself to your system if I moved over there for a while which I more than likely won't but $2.50 a liter? And you guys have 8 gallon gas tanks?
I guess it would be kindof hard to go too awfully far anyway eh? Are there ferries from the big island over to the mainland or is that not an option. Of course the mainland for you would be another country though...
I can get on the service bases (ARMY, Navy, etc) around here due to a "injury" during the Vietnam whatever you want to call it so I get a 100% disability check and the benefit of being able to go on the bases which have no tax but even then they have jacked up their prices sometimes to match what it would cost for a taxed item (called AAFES).
I remember back (many moons ago...) when I was a small tyke and in the US we were having "gas wars" where there was a lot of competitiveness and one one side of the street the price of gas would be 13 cents and on the other side 15 cents but those days are LONG gone.
Hey we could all move down to where the prices are still 50 cents a gallon!
NOT! I guess I should now count my blessings as far as the gas prices but we are still bitc*ing around about our prices and have some good senators trying to make the oil companies tell the truth when it comes to what the prices of oil are when it really comes down to it. They create their own supply and demand stuff as you are probably well aware of and in reality we should more than likely all be paying the same prices for gas as the sandy countries way down below you on the map...
