Someone that goes from 15mpg to 14mpg is spending a lot more money with that seemingly small 1mpg change.

As alluded to elsewhere in this thread it all depends on the purpose.
For practical everyday driving I'd much rather have a feel for distance/volume, I know how much fuel my tank holds, I can estimate how much fuel I have left based on the fuel gauge then I can estimate based on driving conditions how far I can go before my next fill up. With basic multiplication and observation when I was driving a lot I used to do this on a near daily basis to plan my driving over the next few days.
