I have to idle my 2015 car in the winter so that the windows don’t fog up. If there was a way to get the defrost to turn on at full blast with hot temps and not running the car I would be all for it.

Wait, that makes no sense in the context of the above argument. For the windows to fog up, you need to sit in the car right? How long do you need to sit in your car until they fog up? Why are you sitting in your non-moving car for so long? And how often does that happen? In our cars it takes about 10 minutes in cold winter before the fog comes up when around 2 people sit in it, unless it is raining and we just jumped in wet a minute ago. And it's gone a minute after starting the AC again. And one is a small car 2 week short of being 20 years old. From this viewpoint I cannot possibly understand your reasoning? Are you trying to find an excuse to disable Start/Stop?

  > For the windows to fog up, you need to sit in the car right? False. In autumn, when temperatures are low and winter comes (minuses) the humidity is really high. I can't tell you exactly what must happen, but I'v had fogged windows in the morning.

Aftermarket 12v defrosters exist.

  In Scandinavia, very many (probably a clear majority) of cars are equipped with 230 V heaters. There's a connector in the front of the car, you plug the car into an electric socket which has a timer. It goes on in the morning an hour before you plan to leave, and heats up the engine block (heating resistor in the coolant) and optionally there's a Schuko socket in the front passenger's feet and you can plug a heater with a fan there, so that the inside of the car is warm and dry. Both the engine and the cabin heaters range from 600 to 1200 watts.

  Most cars can have one installed at the dealership too

The quickest way to get rid of foggy windows is max heat, with AC on.
