So you're suggesting that this isn't a valid sample.... OK I'll (hopefully) find sufficient reason to go on a more extended freeway trip that will give me a more true figure.

-traffic
-rate of acceleration/deceleration
People like to complain about the way EPA ratings are determined--but there's a reason it's best to do it on a dyno in a temperature-controlled lab: you remove all these other variables.
