Do you know something you aren't saying? I don't see anything that is obviously 'very well' thought out. It seems the reverse. They are treating the car exactly like every other gas burning car, in which is obviously is not. The lack of cues are enough to allow a percentage of people in certain circumstances to not know the car is still on. It goes even further than the links above with Push Button issues, as this car is virtually silent when turned on.I believe GM has gone over this thoroughly, and as implemented, it is very well thought out.
