Meaning you have halved your fuel use - given you'd drive it the same distance.

But then I switch from using gasoline, to using E85 ethanol.
I lose 10-15% mileage, yet I'm still getting higher mileage per gallon of fuel that I was with the old car.

If the 15 mpg is 100%, the 30mpg car is at 50% , but by using E85 you'd then get back up to 55% - 57.5% fuel wise.

The question: Is this still considered progress?

With ethanol from renewable sources, it surely is.
There's only 15% gas in E85, so you've reduced your gas-use to 8.25 to 8.6 % of what you used with the 15mpg guzzler.
