Yes, I've seen some of these. They are all designed to allow installation of the driving controls on either side for global sales, of course, and I even saw one that the user could shift the console from side to side (presumably only while stopped.) I'm talking about a second, short-term-use, driving console in the passenger seat to let the passenger take the wheel while driving.

Today, we're seeing more and more evidence that cell phone conversations, even with handsfree, may impair driving. The prime use for this would be to let the driver safely take a call. People really want to be able to take calls on their car trips.
