Mercedes-Benz has gotten into the habit of bringing some rather forward-looking concept cars to CES. Two years ago, the company gave some of us late night rides down the Las Vegas Strip in its Smart Vision EQ concept car, even if that was actually a remote-controlled show car rather than a functional self-driving machine. I'm not on the ground at CES this year, so I didn't get to see this year's Mercedes concept in person, but it looks even more out there. It's called the Vision AVTR, and the name is a clue—it was designed together with the people responsible for the movie Avatar. Yes, really.
