How would the system know you were at a stop sign and not just slowing down to yield or for slow traffic or whatever? I personally don't like lights flashing on my dashboard, so I might intentionally avoid coming to a complete stop to avoid seeing the light. In all honesty, I often avoid coming to a complete stop to reduce wear on my clutch and brakes. I wouldn't want my car complaining about it.

Dwane, in answer to your question, the light would only indicate when you have made a full stop. I wrote that I'd consider a red light for a rolling stop, but you're right, that's a problem I don't have solution for, so I just mentioned it. I don't actually support it.

Also, I used to have an 'shift' light on a car and you're right, it was annoying--I'd sometimes shift early just to avoid it.

But I also have teens driving that I've followed to school and they didn't make full-stops. I can't think of a way that the car can 'reward' a full stop.

You've introduced that a full-stop may not be necessary or desirable and I think that's a defensible position, but not to a policeman. Rolling-stops do cause some accidents, but I've no idea of the number.

As for the car 'complaining', since it's coming anyway, I'm just pointing out more things it could recognize without much effort.
