So, I remember reading somewhere that before the Gas crisis cars on the western world got so long that the average car on the US was five to six meters (or 19,6 feet) long, one example being the Lincoln continental that was 5,5 meters
Assuming there is no gas crisis, how big can cars get as the GDP levels continue to grow worldwide?
Engines were going to be gutted for Emission air pollution reasons, the CAFE fuel economy would be after the crisis
The 1970 Clean Air Act, requiring a 90 percent reduction in emissions of hydrocarbons (HC), carbon monoxide (CO), nitrogen oxide (NOx) from new automobiles by 1975
Also, the long term rise in gas prices is still going to happen once China, India, and the rest of Asia start really growing. That will do it by itself.
