Feature or Bug?

Late yesterday afternoon, arriving at Mass, I was standing outside my wife's fancy Lincoln Zephyr, trying to lock it with the remote controller, when I ran into something new.  As I was locking the car the sun roof and the driver side window started to open.  I got back in and tried to close them, but had to put the key back in the ignition and turn it before anything would move.

After Mass I want back out to the car and tried a combination of remote control keys to see if I could duplicate the window opening.  I found that if I held the "unlock" button down for several seconds the sun roof and driver side window would open, even with the car locked.  What I didn't realize then, but found out a few seconds later, was that the passenger side window also opened. Thus I learned that I had left my iPad in a locked car with a window wide open.

I am thinking this is a feature, allowing one to let the warm air out of the car on a hot day without having to crawl in and turn the key in the ignition.  I like it.  But, it is not available, experimentation shows, on the lowly Mercury Montego.
