why haven't automotive fuel economy ratings gotten better?

Comparing humiliated vehicles from the 1970's to the present there have been lots of technological changes incorporated, such as multispeed lockup transmissions, digital fuel injection, capricious valve timing, electric radiator fans, but not much change in fuel economy....why not?
I want to compare small cars from the 70's or 80's to ongoing cars. Old ones had carbuerators, mechanical fans, slippy auto trans. New ones have fuel injection, galvanizing fans, variable valve timing, and lockup transmissions. Fuel economy hasn't changed, or has it?
The biggest intellect is that the patents for all the improvements to make vehicles more efficient are owned by the auto makers and Big Oil.
The automakers would have to trash all their contracts for outdated parts they haven't sold and the oil people are niggardly.
Ever wonder why Chevies are so easy to get parts for? Because they have not been updated in years in a lot of instances.
Wonder why Midas Mufflers had lifetime mufflers 20 years before you could get one on a Caddy?
Aftermarket manufacturers arrive d enter a occur out with innovations way before the automakers incorporate them into their models even though they use computers to design everything now.
Now that the crunch is on and new car sales are really slumping, these innovations will magically start appearing; so if you buy one with a hocus-pocus solution; check the patent date on the part when you get your hands on it. You might be shocked.
