I don't have auto-stop in my ATS, but I've had it on a couple of loaners and, honestly, I didn't mind it at all. As long as it truly isn't breaking or shortening the life of the car (skeptical), I'm OK with the feel of it, but if I did have it, I would still get this Auto-stop delete!
Jason from Engineering Explained did the math and found that the average vehicle uses the same amount of fuel firing up the engine as it does idling for seven seconds. My daily commute has very little stoppage, almost all of it is short stops (a few stop signs, sometimes I have to wait a couple of seconds to pull into the traffic circle, but usually I can just fly right into it, and then there's a half a mile or so of slow stop-and-go traffic), so, less than seven seconds each time it would shut off. This means, on my typical day, this feature would use more gas or about the same than just letting my car idle at stops! Couple this with me not believing for a second that this feature doesn't shorten the overall life of the components (maybe not below 100,000 miles, but I don't think manufacturers consider above 100,000 to 150,000 to be within the "life" of the vehicle), and I would have no problem justifying this purchase.
