You can do the same thing directly from googlemaps. 'maps.google.com'
Why do we need a middle man?
Google maps seems to do exactly the same thing. You set up driving directions, it tells you the route. You click on any step and it shows you a map of the area and a photo of the street/intersection, if available.
I've tried this in both IE and Firefox and can't find this extra 'Drive' button. I only see a 'Print Driving Directions' button. ???
