B4 I had the AH I would shut off my Cavalier at lights, and I've trained my wife to do the same in her SUV. This does not address the problem of traffic jams, though- where one is coasting, stopping, sliding 20 feet forward, stopping, rolling at 8mph for a block or 2, etc. This is identical conditions to a Beltway jam. Granted, our AHs are still doing better than any other 6 cylinder out there in the same situation, thanks to autostop, but it can be soo much better- the software could allow the 'eco' mode to be used in these sustained low-speed (crawl) conditions, where any acceleration is slow and short-lived at best. The constant shutoffs dont bother me- its knowing that I COULD be running on 3 cylinders instead of 6 at 5 miles per hour that do. I have no illusions as to the complexity of thei 'simple' enhancement, so I do not hold my breath. But the potential is there. Any chance the AH computer OS is Linux> ...maybe the freeware community can hack it and add the feature (lol).
