I guess what I mean is, this is not a finished product that's a regular car with a "hands-free" mode; it's a prototype for a fully-autonomous driver-less car that's still under active development.

I.e. the reason that this exists is not to have some mostly-autonomous driver-assistance in place right now; that's useless to Uber. Rather it's part of the process of testing and improving the completely driver-less cars that they're working on.
