I don't think the claim of saving fuel is in contention but the overall value to the customer. If your someone like me who keeps a car for infinity (or until a deer does it in) does the increased maintenance cost and increased complexity justify the change.
Before you argue, complexity and increased parts count will reduce the reliability while increasing the cost, and at the end of the day the customer pays for it. If you were offered something like the chevy cruze with everything but the essential's stripped off of it, and I mean the essentials, ALA 1976 type car. Power steering, windshield wipers, seats, and heater ect. and you could get it for $7k Vs. the 2017 cruze with airbags, a/c, start/stop, ect. ect. for $23k
Shouldn't you be given the choice????????
