The answer to your question is very complex and requires more knowledge than the average person has. The Prius is not the most fuel efficient car. the Honda insight is the most fuel efficient car today at 65 mpg, prius only gets 55 mpg in 2008; however the insight only has 2 seats and 2 doors; the Prius 5 seats and 4 doors, big difference. Now the answer to your question. Requires some knowledge of history. A large number of Japanese people (not sure if were hundred of thousands or perhaps millions were killed in a matter of minutes with a very sophisticated and technologically advanced weapon of mass destruction in 1942. That was a lesson that not Japanese has forgotten to this day . Very quickly they realized that they were lacking technological knowledge and that if they want to be the leaders in the world they needed to compete in technology.That was and still is their priority. look in the back of your television, your camera, your cellular phone or any of the most advanced technological device available in this planet, where is made. American car manufacturers at the beginning of the century were the pioneers on technological innovation; in the last 20 years more or less, their priorities have shifted to become the most wealthy and profitable. Technology and innovation is not their priority. I have a full time job and make only $11 dollars an hour. I have 3 vehicles in the family that require frequent maintenance and repairs; if I go to the dealer they charge me $60 per hour of labor, if i go to the local repair shop they charge me also $60 per hour of labor. Two of my vehicles are Toyotas. The reliability of Toyota is unsurpassed by any other brand in the world. Isn't that amassing?. That explains why American manufacturers are not longer the number one sellers of automobiles in the U.S.A.
