Via the app wouldn't it be nice to tell your car when you're ready to leave? You could set the desired temperature, seat heaters, as well as what time you'll be leaving (through simple toggle buttons on the app). The car would know and start to warm up so you have everything ready when you get to your car. For example, if you're out to eat and you are leaving around 7PM. You sit down to eat - toggle your settings - eat...then when you're done with your dinner you walk out to a perfectly prepared car for your ride home.
Anyone else have this thought? Maybe it has been discussed already...?
