Combined EPA estimated mpg is based on 45% highway and 55% city driving, FEcomb = 1 / (( .55 / city FE) + (.45 / hwy FE))
That isn't fair for those of us that do far more city than highway driving, where it should be closer to 10 and 90%, makes us look bad!
That ratio would be:
FEcomb = 1 / (( .90 / city FE) + (.10 / hwy FE))
Using that average and excluding my recent trip to Twin Lakes, my combined mpg rating for my car would be 18.5, which is exactly where I'm at
Anyone else do far more city than highway driving? And find that the 45-55 ratio doesn't correctly apply to you?
