I work for an energy company, the name of which will not be posted here. Regardless of how "tin-foil hat" people think that this statement is, I believe that the US will not allow cars that are ecologically friendly into the country because there is too much money to be lost by the Car and energy companies. Why do you think that the USA REFUSES to join the Kyoto Protocol? Because there is more money in high pollution/low gas mileage vehicles, "no money" in hybrids or fuel efficient vehicles (The more a car drinks, then the more you have to spend filling it....thereby further lining their pockets). I don't think that the US wants to let in cars that will further damage our failing car industry...and even on that note, take MILLIONS (if not billions) out of the pockets of those ruling class folks that are directly involved in US Car/Oil markets. Just my 2 centavos.
