We've been perplexed by Lexus' "dark side of green" motif for the 2011 CT 200h ever since it was unveiled at the New York Auto Show this year, and even after getting a look at the interactive "Dark Ride" movie, we're left, well, in the dark. And not in a good way.

The mission behind the interactive side of the video is to "bring the CT 200h home before dawn." It seems the CT 200h has a date with a pumpkin carriage and a glass slipper, or something. Once you've passed the "interview process" and been deemed worthy, you have to help deliver the car, in the dark, without letting it get photographed. But you're not the driver. You're the passenger, or "baby sitter," meaning that you're basically just along for the ride, aside from serving as navigator and occasional decision-maker.
