only about 1/2 way to looking like a Transformer, and no where near looking like it can become anything vehicle related... they must be hoping a really rich blind person wants to buy it for very slow parties (top speed 6 mph)

it's a waste of time to watch the video, as it's fast moving drone camera is used to cause the viewer to forget that this isn't changing from tall robot, to vehicle... yes, it can move hands, no, it doesn't do a damn thing with them. It doesn't have a bipedal form, or a car/vehicle form. It can move the torso, a little. That's about the sum of what it can do. Nothing more than nice robot paintjob. 

There's a Boston Dynamics engineer falling asleep just hearing about this.
