Engadget video highlighting how the QNX concept car takes advantage of WATSON, AT&T's cloud-based natural-language speech engine. Here's another video, from Jordan Crook of TechCrunch, in which AT&T's Mazin Gilbert describes what WATSON does and QNX's Derek Kuhn demonstrates how WATSON works.
The entire video is interesting, but jump to the 3:30 mark if you want to see the car. The video provides a very nice view of the QNX-equipped dash, btw.
The Engadget video and the TechCrunch video were both shot yesterday at AT&T's "Living the Networked Life" event in New York.
