OK... here you are full of crap. The energy to make a car can come from renewable resources or resources that do not produce CO2 as waste products. I also want proof that making a car uses so much energy . If your SUV gets only 18 mpg, well, I can't see how driving it 12,000 miles a year wouldn't use more energy than making it. A gallon of gasoline has about 41 kw-hr of energy- most of it is wasted by a gasoline engine. I don't see how it could possibly take more energy to make a new car than to drive it around.

You obviously drive a sports car that exceeds the needs of almost all drivers, realisticly. You do not need that kind of acceleration to drive a car. If you need that kind of acceleration, you are driving wrong (likely speeding to pbutt, rather than looking for openings).
Prius was driven by professional drivers in the EPA tests, none of whom tapped the accelerator scarefully. In the real world the Prius, at worst, seems to get around 40-50 mpg on highways, and in the mid 30's in very cold winter, as the cold saps the energy out of the batteries. Some people of course get much better fuel economy.
Rotational force to move a wheel, in this case.
