I don’t see why you guys think it’s amazing? They have just connected all objects in video to videos timeline – you can’t really change anything but just rewind and forward the video. Amazing for me would be if by moving one object in the video the end outcome would be different...

"They have just connected all objects in video to videos timeline"

The technology is awesome if it's powered by software that interprets what elements of a video constitute an object, and then connects those elements to a timeline in a single, automated swoop. I've assumed that's the case, but I could be completely wrong.

Whether they actually capture objects is unclear. You could get the same results by building the vector field of motion (pixelwise) and then detecting if the mouse moves along the vectors (fast forward) or against them (back). So, you aren’t "dragging" the car with your mouse - your mouse is simply following the path of the car.
I think where this technique really shines is when you don't have any idea when a particular object moved. Like in the parking lot example, you could just click and drag on an arbitrary car to immediately jump to the time when that car moved.
