Anyone own a Nissan Altima Hybrid and use it primarily in the Bay Area? If so, what sort of gas mileage are you experiencing?

It seems like temperature, traffic, and hills will all affect overall mileage, so I'm curious what the experience is in our area.

It would be a nice addition to this site to be able to filter the reported gas mileage for all the cars by a given radius around a ZIP code (or some other location selection). It's seems like everyone would be benefit from being able to see mileage for the specific area that they live in.

Thanks in advance.
