Gas Mileage

Funny thing happened on the way to work this morning...

I was listening to an old Jack Benny program from April 1933 and it was a time they were collaborating with Chevrolet and giving away thirty cars. That's a big deal. To enter, you apparently had to explain why you liked Chevrolet so much.

"A lot of entries spoke of how ECONOMICAL a Chevrolet was, getting 20, 22, 24, sometimes even more, miles to the gallon."

What the hey? So in seventy years they have not improved the gas mileage of cars? Maybe, they've gotten a bit better on some models, but we still talk about cars getting 20 or so mpg.

Computers have gotten faster and better. Everything technical has gotten faster, better, and more economical. But cars still get the same gas mileage? Or is that the limit? Was it truly perfected to start with?
