Despite all of Google' effort, they still rely too much on USGS published maps. For example, just 6 miles from the GooglePlex is a road in Newark with a gate [1], but Google doesn't know you can't drive on it. They're doing a good thing, but unless you can see that Google has driven the route and has published street view, you can't entirely trust them. [1] 37.515696 -122.050873
