A survey of gas prices collected the numbers from gas pumps in 155 countries and placed the US as number 111, meaning prices are 45th cheapest out of the countries surveyed. The reason prices in the US have been comparably low is that taxes on gas have been kept to a relative minimum when measured to international standards. Some experts say that Americans are extra sensitive to hikes in gas prices because we've been spoiled by cheap gas in the past, and feel any increases more acutely than countries who are used to being taxed more. The cheapest gas is found in fuel-producing countries.
