Some U.S. citizens are driving across the border to buy gas in Mexico for $2.80 a gallon. The fuel is cheaper because Petroleos Mexicanos, the state-owned oil company, controls prices with the assistance of the Mexican government. The government keeps prices as low as they can because they don't want a public revolt. Gas is also less expensive because Mexican environmental laws are not as strict as laws in the U.S.. $2.80 in U.S. dollars is equal to a little over 32 Mexican pesos.
