At first, it seems like we've had street level photos like that (pagesjaunes.fr is the oldest example I know) but I've never seen something like that where you can actually grab the car, move it on the map and see the view from your car change in real time with amazing responsiveness. You can also drive with the keyboard. It's no PGR3 but it's damn impressive for a web application.
