Google has added a neat feature that combines Google Maps driving directions with StreetView. When you’re looking at your list of directions, look for the little camera icon next to each item. If you see one, then you can view those directions in StreetView. It draws a blue line with large arrows inside of the StreetView window to help show your route.
Google has created a video that shows off this new feature. After you’ve watched the video, try it out for yourself. If notice anything interesting during your trip, show it off in the Google Earth Hacks new StreetView section.
