Exactly! They will only offer solutions maximizing their return on investment. That return is determined by the added value percieved by the customer. And what does the average car buyer percieves as far as fuel economy is concerned. Yup, the sticker in the driver's window in the showroom.
That's why we don't see idle-stop much here while it's everywhere in Europe (~35% of the time in the urban part of the NEDC is idling time vs ~19% for the EPA FTP-75 cycle).
