Gas in Saudi Arabia is $.62/liter....about $2.65 gal.. USD. Not all that cheap when you consider everything.
Russia is about $3.32/gal..
Hong Kong is almost $11/gal.!! Not liter, gallon.
The cheapest gas in the world is in the country with the most oil reserves in the world, which is nowhere close to The Middle East.
Venezuela has gas at a whopping 7 cents/gallon. Because the 'people' own it. Not the country or some corporation(s).
