First, there was the Google Street View Car, a special vehicle with a 360-degree camera mounted on top that brings us all that detailed Street View imagery. Then, Google engineers invented the Trike, a tricycle with a camera that can reach all those places where Street View Car cannot go.
Neither of those two vehicles, however, can venture out in the snow, and this is why Google created the Google Street View Snowmobile. Just like the Trike, it was invented by Daniel Ratner, and it was created especially for the Winter Olympics in Vancouver, so expect some beautiful imagery on Street View during the event. See a video introduction to the Snowmobile below.
