Google Maps has integrated driving direction into Google Street View.
"By viewing Street View images alongside directions, drivers have visual context for intersections and action points along their route, enabling them to be aware of landmarks and other factors such as tolls, speed limits, size of the road, and the availability of parking at their destination."
"Street View, originally launched in May of 2007 in 5 cities, now provides interactive 360-degree street-level imagery in 44 regions across the country. Integrating Street View with driving directions provides those living in or traveling to these regions with another powerful, useful tool to help them easily navigate their surroundings. Street View was also recently made available through the Google Maps API, allowing developers to utilize Street View functionality to enhance their services"(Google Press Center).
