I'm not sure if this is the same type of un-easyness you're referring to, but the whole video made me feel physically un-easy. The video is rendered at a very low framerate, and that combined with the fast motion of the camera is almost nauseating. Aside from the low FPS, at 14-15 seconds, when the camera zooms past two skyscrapers on its left, I very quickly noticed (without having to pause the video and examine it) that the the buildings had low-res textures compared to what you would find in a video game or compared to real life. Perhaps this, combined with the low FPS, is what makes the experience so uncomfortable. But while this may not be good for close-up fast moving shots, it certainly does seem to have useful applications (see 0:27, 0:33, 0:45 in the video). And it's still very impressive how far our technology has advanced - the first heavier-than-air flight was about 100 years ago, computers are also just decades old, and yet right now we are using algorithms to combine satellite imagery and images taken from the surface (street view) to make a 3D model of our world that is explorable in real time (the Google Maps website has this 3D view feature on it).
