I hate to admit this, but Microsoft have managed to outdo my favourite website ever, Google Maps. Their new preview site features “immersive city navigation”: not only do you get the satellite photos a la Google Maps, but you also get a ground-level shot as if you were driving a car. As you move the car around on the map, the view out of the car windows (front, left and right) changes accordingly. (Best viewed in full screen.)
It only covers Seattle and San Francisco so far, but this could be pretty awesome if they roll it out to other cities (London? Soon? Please?).
