I was prepared to be skeptical but this is actually pretty cool. The thing that's never discussed, however, is that these demonstrations always require fast, accurate, and external motion capture systems (Vicon, etc), and wouldn't work outdoors. I'm not aware of anything that is currently available that will get close to this level of speed and accuracy for vehicle state estimation, which will make it very difficult to apply these techniques in real world situations.

Very cool proof of concept though.
