My Room with a View

I've always thought of my car as a mobile room.  On cold days, I can jump in my car and park it in the sun.  I get sun streaming in from everywhere, with complete protection from the cold air and wind.  When it comes time to eat, and it's too cold to get out of the car, no problem; I just start my mobile room and go through a drive through and then park somewhere in the sun for a nice indoor/outdoor picnic.  It's the best of both worlds:  food and sunshine with a comfortable chair and no wind.  Also no ants.
