I use the system on occasion, when traffic is light but traffic lights seem long. In heavy traffic I turn it off but then turn it back on when needed. I wouldn't bother with re-coding either. I like using it with AUTO Hold since I just have to touch the gas and it re-starts. On some occasions I turn the steering wheel to start it before the light changes. Once in a while, while sitting at a very long traffic light, the car will turn itself back on without any prompting from me.
