Agree with OP, will be interesting to hear how this works in the real world.

Sounds like more trouble than the amount of gas it will save. I wonder if this feature cost more to put in than it will save me in gas for the lifetime of the car. I think manufacturers are offloading too much costs to the consumer because of CAFE.
Hopefully it will be reliable otherwise you will spend more money on repairing the transmission from all this decoupling than money saved in fuel efficiency.
