I average 8 mph because I'm always in city traffic and can't beat the 40mpg you are supposed to get in a city with my crv hybrid.

Does anyone have any insight into when the supposed advantage of city driving becomes a disadvantage due to too much stopping?

Or is anyone proving this to not be the case?

If you don't have experience or special knowledge about vehicles averaging less than 10 mph for all their driving, maybe your comments won't be as valuable.

edit: i did some more research to add to my point. The epa uses 21mph average for its city ratings and tops out at 56mph. The citywide speed limit in NYC is 25mph, so no one there will ever match epa conditions.

As one commenter has pointed out, 0 mph average is obviously bad mpg. 21 mph is better mileage than 48 mph for hybrid cars (what the epa uses for highways). Where is the number below 21 where it starts to get worse?

Despite the myth that "city" driving gets better mpg than highway, New York City hybrids do not meet their epa ratings.

According to a study of city government-used vehicles, even a prius gets 40.6 mpg instead of the epa rating of 51.

I get 34 mpg in a 26 CR-V awd and average 8 mph.

If anyone has a different experience, I'd like to hear it.

edit: I see there is some disagreement over what constitutes a real city. The point of this post is just to make it better known that in some extreme city conditions: NYC, London, Cairo, Mexico City, Sao Paolo, Mumbai (usually where average speeds fall below 10mph)... the benefit of city vs highway driving no longer exists. From the comments I can see that is something most people are not aware of or do not want to accept.
