Only goes so far. The interface between the garage door and the frame of the house is difficult to seal perfectly. Always going to be drafty. Also, you can’t put particularly thick insulation on the garage door.
I live in a cold climate. I have a 2 stall garage and the north facing insulated doors seal very well to hold in the heat. In fact the whole garage is insulated and I even heat it. Holding the building a 45F it takes 2 years between refills with a 200 gallon LP tank. And this is with temperatures than hit -40F over night with highs still well below 0F for several days or weeks at a time. And even unheated, that garage will never drop below freezing over an entire winter.
If you a drafty doors, you are doing something wrong. Fix them.
Even if the garage is attached, there will be an exterior door between the garage and the house proper that will be as heat loss resistant as your front door. So I don’t know how you get anymore heat loss than you would from any exterior door in the house. In fact, that door will have LESS heat loss than your front door because it’s shielded from the elements that your front door isn’t.
Honestly I was half joking, but seriously don’t most homes have extra insulation between the garage and the rest of the house? Are you guys heating your garages?
They do. A garage with a closed door acts like an air gap, meaning you get some extra insulation for free. It’s far from perfect, as the garage door itself can’t have particularly thick insulation, and the interface between the door and the frame is difficult to seal completely. Still, even an uninsulated garage with a closed door will typically be a bit warmer than the outside in the winter.
What’s special about the door or do you mean just opening it? If the latter, that still won’t prevent it from collecting at the ceiling and you’d better hope you remembered to open the door.
But you cannot do that in the garage (unless you like huffing exhaust fumes).
And if you spend a couple hundred bucks on insulation, you don’t need to preheat anything in your garage either.

You can’t open a garage door remotely? I can.
Exhaust fans are not new or unapproachable tech.
They are also not a common fixture of garages.
But they are a life and death safety device in the scenario you describe. Hvac equipment.
The majority of garages I’ve seen have a garage door so the fumes don’t just build up in the garage.
Which means that your home then has increased heat loss because the garage door is open.

Would you have a large impact on your home from having your garage open for 15 minutes or so every day?
Eh, I don’t even have a garage, and my place stays warm just fine. It’s just a few minutes
What the hell are you talking about? Listen to yourself
