Based on my own experience and 2 coworkers, 45 on the highway sounds about right. I assume everyone/Honda is protesting the city rating of 26? I can see how heavy stop-n-go and crawling traffic (that disables auto-stop) could get that low.

During a recent trip to Chicago, I was running about 32 mpg in bad city traffic. Acceleration just kills the mpg. In decently flowing city traffic, I was running 50-60 mpg. I think it depends heavily on the test environment.
