HYPERMILING: Now, A Real Word! Mostly.

"Hypermiling" was the New Oxford American Dictionary’s word of the year.

It vindicates all that hard work . If one gets philosophical, one could ask, "If one is a hypermiler, is one really doing anything? Can one perform an action that has no dictionary-approved verb?" (One is also the philosopher’s preferred pronoun.)

Now it’s official. You’re hypermiling. Sounds a lot better than "driving slow," anyway.
