Remote deicing of the windows in the winter sounds rad and more then just a gimmick.

Even with gloves on it can be quite cold to remove the all the ice from windows. Or you sit in the cold car for 5 minutes waiting for it to defrost on it's own.

And yes, if your climate control is broken I would pay to fix it.

Edit: When you share a car and have no dedicated parking spot the location information can also be interesting.
