Has anyone noticed that the Intelligent Key allows you to lock the doors, leave the car running, and take the key with you without so much as a warning or a beep? At least that's the way my 2005 MO operates. My wife actually left the engine running through an entire 4 hour football game because of this. The engine is so quiet we didn't notice it until we were about to get back in the car. I would think Nissan would have incorporated some kind of auto-shutoff feature or at least a warning beep in the absence of the key.
